Trading In Your Car in Thailand: How It Works, What You'll Get and What If You Still Owe Money
TalataCars
A car trade-in in Thailand means selling your car to a showroom or dealer and putting the money towards your next one. Cars still on hire purchase qualify too: the dealer pays off the old loan and the difference goes to your down payment. Expect less than a private sale. Talata, a Thai marketplace listing used cars from many sellers in one place, helps you check your car's value before you walk in.
What is a car trade-in, and who takes them in Thailand?
A car trade-in is when you sell your old car to a dealer and the agreed value is deducted from the price or down payment of the car you buy next. Thai buyers call it "turn rot" (เทิร์นรถ), so you will hear that word at most showrooms.
The dealer, not you, handles the paperwork. They pay off any remaining finance and take the car to the Department of Land Transport to change ownership. Your part is to hand over the car and documents, then collect your new one, usually on the same day or close to it.
"Ti turn": who actually values your car
Sales staff will say a car "ti turn" (ตีเทิร์น) for a certain amount, meaning that is the trade-in valuation. The person setting that number often isn't the salesperson in front of you. Many showrooms send photos and details to a partner dealer or a used car centre and relay the figure back.
That valuation has to cover reconditioning (paint, tyres, a proper clean), the dealer's margin and the risk of the car sitting on the lot. It will almost always be below what a private buyer would pay. Knowing why helps you negotiate the right things.
Showroom, used car dealer or a brand's own used car centre
A new car showroom is the easiest route because the trade-in and the new purchase sit in one deal, and the salesperson coordinates finance for both cars. Watch how the trade-in value interacts with the new car discount; one number on its own can look better than the whole deal really is.
A used car dealer suits you if your next car is also second-hand, or if you simply want cash. Prices are more negotiable. Pick a dealer with a real showroom and get everything in writing.
Some car brands run their own certified used car centres that take trade-ins and value your car free of charge at the showroom. Terms change with each campaign, so ask for the conditions in writing before you commit.
Trade-in or sell it yourself: which leaves you with more money?
On money alone, selling privately usually wins. On time and hassle, the trade-in wins. The real question is whether the gap is worth the effort and risk you take on yourself.
Side-by-side comparison
| Trade-in | Sell it yourself, then use the cash as a down payment | |
|---|---|---|
| Price you get | Below market, because the dealer needs a margin and has reconditioning costs | Closer to market, depending on how you negotiate |
| Time until you're paid | Usually done on the day you take the new car | Depends on how fast you find a buyer |
| Work you do | Hand over the car and documents | Photos, listing, viewings, negotiating, the transfer |
| Car still on finance | Dealer settles the loan | You coordinate the payoff with the buyer |
| Main risk | Dealer doesn't settle the loan or transfer on time | Scammers, no-shows, payment fraud |
A worked example
Say cars of the same model, year and similar mileage are listed at around 430,000 baht. These figures are made up to show the method, not real market prices.
Selling privately, you agree on 410,000 baht. At the showroom, the dealer values your car at 360,000 baht and offers an extra 30,000 baht off the new car if you trade in. Together that is 390,000 baht of value, 20,000 baht less than the private sale.
Now look at that 30,000 baht discount again. If every buyer gets it anyway, trade-in or not, the real gap is 50,000 baht. That is why you should ask for the trade-in value and the new car discount as two separate numbers. If selling yourself makes more sense, the guide on how to sell a used car in Thailand covers the process, and where to sell a used car compares the main channels.
How to trade in a car in Thailand, step by step
- Check what your car is worth: look up the reference price on ttb bluebook (free) and compare listings of the same model, year and mileage.
- If the car is on finance, get a written payoff quote from the finance company with the date it is valid until. The dealer can request it for you, but have your own figure first.
- Get valuations from at least two or three places, for example the showroom where you are buying, a used car dealer and a brand's used car centre.
- Negotiate with the trade-in value and the new car discount written as separate lines.
- Sign an agreement or vehicle receipt that states the trade-in value, when the dealer will pay off your loan and when ownership will be transferred.
- Hand over the car with its documents, both keys and the service book.
- Follow up until the transfer is done, ask for a copy of the updated registration page, then tell your insurer.
Step 7 matters more than people think. Under the Land Traffic Act B.E. 2522 (1979), a change of ownership has to be reported to the registrar within 15 days, with a fine of up to 2,000 baht if it isn't. Putting a transfer date in the agreement gives both sides the same deadline.
Documents you need to trade in a car
The core set is the same as any vehicle transfer. What changes is who holds the registration book and who files at the Department of Land Transport.
If the car is paid off and you hold the registration book
- The original vehicle registration book (the blue book)
- A copy of the owner's ID card
- The transfer request form, filled in and signed by both seller and buyer
- A power of attorney with a copy of the attorney's ID, if the dealer files the transfer for you
- A sale agreement, receipt or vehicle receipt showing the price
Some dealers also ask for a copy of your house registration. Bring both keys. Fill in the buyer's name and the date on the transfer form and the power of attorney before you sign them. The Talata guide to vehicle transfer documents goes through each form in detail.
If the car is still on hire purchase
A financed car's registration shows two parties. The finance company is the legal owner, and you are the registered possessor. The original book stays with the lender until the loan is paid off.
You will need a copy of your ID, your current hire-purchase contract and a written payoff quote. Once the dealer pays off the loan, each lender handles the release differently. Some banks file the transfer themselves; others, such as SCB, post the registration book to you after a deposit so the transfer can go ahead. Timing varies too, and ttb says the book comes back about 15 business days after payoff.
Extra documents for foreign owners
If the car is registered to a foreigner, the Thai ID card is usually replaced with a passport plus a Certificate of Residence from immigration or your embassy, or a work permit. Requirements differ between offices, so confirm the list with the Transport Office before the dealer files.
Can you trade in a car you still owe money on?
Yes. The dealer uses the trade-in money to pay off your existing loan first, then settles the difference with you. The maths is one line: trade-in value minus payoff amount equals what goes towards your next car. If the result is negative, that is what you need to top up.
Get a payoff quote before you talk price
Your payoff amount is not the remaining instalments added together, because paying early earns a discount on interest that hasn't fallen due yet.
For hire-purchase contracts signed by individuals from 10 January 2023, the Office of the Consumer Protection Board (OCPB) sets a minimum discount based on how much of the contract you have paid:
| Instalments already paid | Minimum discount on unearned interest |
|---|---|
| Up to one third of the total | 60% |
| More than one third, up to two thirds | 70% |
| More than two thirds | 100% |
Contracts signed before that date follow their original terms, so ask the lender directly. Get the figure in writing with a validity date, since it changes every month. The guide to selling a financed car explains how each lender issues payoff quotes.
When the trade-in value is more than you owe
Say the dealer values your car at 360,000 baht and your payoff is 280,000 baht. The dealer pays 280,000 baht to your lender, and the remaining 80,000 baht goes towards the down payment on your next car. Some dealers will pay it out as cash instead; agree this up front.
When you owe more than the car is worth
If the valuation is 300,000 baht and the payoff is 330,000 baht, someone has to cover the 30,000 baht gap. The simplest way is to pay it yourself in cash.
If the dealer suggests another way, ask to see the loan amount and monthly payment on the new car before you agree. If your old shortfall is added to the new loan, you will be paying interest on your old car's debt for years.
The other route is to skip the trade-in and find a buyer willing to take over your payments through a formal hire-purchase transfer with your lender. The guide to changing a car hire-purchase contract covers the steps and fees.
How to get a better trade-in price
Check the reference price and real listings first
Walking in with numbers changes the conversation. The ttb bluebook price is a starting point, but it isn't the same as the Department of Land Transport's assessed value, which is only used to calculate stamp duty on the transfer.
The closest thing to a market price is what similar cars are actually listed for: same model, close in year and mileage. Used car listings on Talata show that range. The guide to estimating a used car's value explains which factors push the price up or down.
Get several valuations and keep the discount separate
Valuations vary between dealers because each one specialises in different cars. A dealer that sells a lot of pickups may pay more for your pickup than a sedan showroom will.
Ask every dealer for two figures: the trade-in value and the new car discount. Some offers raise the trade-in value and quietly cut the discount, so the total doesn't move. Separate numbers let you compare offers properly.
Prepare the car and its records
Wash it, vacuum the cabin and take out everything personal. A clean car tells the valuer it has been looked after.
Bring the service book, receipts for tyres or a battery, and the spare key. Fixing small things like a dead bulb or a worn wiper blade is worth it before a valuation. A full respray usually isn't.
Risks to watch when you hand over the car
Don't leave a signed "floating transfer"
A floating transfer (โอนลอย) is when you sign the transfer papers but nobody files them at the Department of Land Transport. Until someone does, the car stays in your name. Speed camera tickets, annual tax reminders and police enquiries come to you first, even though someone else is driving the car. Having your name on the register doesn't automatically make you liable for what the new driver does, but you would need your agreement and handover records to prove it.
To protect yourself, put a transfer date in the agreement, fill in the buyer's name before signing, and ask for a copy of the updated registration page once it's done. If the date passes, chase it in writing so you have a record. The sale contract guide shows what a car sale agreement should include.
Confirm the old loan has actually been paid off
A problem that comes up from time to time: the dealer takes the car but doesn't settle your finance. The hire-purchase contract is still in your name, so if payments stop, the lender comes after you.
Ask the dealer for proof of payment, then call the lender yourself to confirm the account is closed. If something goes wrong, keep the agreement, the vehicle receipt and all your messages, and get legal advice or contact the OCPB.
Tax, traffic fines and insurance
Check for unpaid traffic fines before handing over the car. Fines issued before the handover date are yours to settle.
For voluntary motor insurance, read the "transfer of vehicle" clause in your own policy. The standard wording makes the new owner the insured for the rest of the policy term, but some policies end cover on the day of sale when the car is sold to a business that buys cars, and the insurer refunds the premium. If you cancel the policy yourself, you have to do it in writing and the refund follows the short-rate table in the policy. The simplest move is to tell your insurer the day you hand over the car. Transfer fees charged by the Department of Land Transport are covered in the guide to car transfer fees.
Is the government "old car for new car" scheme the same thing?
No. A dealer trade-in is a private deal between you and a showroom. The government scheme people search for as the "Thailand car trade-in scheme" was a 2026 proposal for state incentives when replacing an old car with a new EV or hybrid. In June 2026 the Excise Department said that scheme would not go ahead in its original form. By August 2026 it had settled on a one-off subsidy for EV buyers paid through the lender, but the measure had not been launched and still needed Finance Ministry approval.
Until a scheme is officially launched, a normal dealer trade-in is the only trade-in available.
Trading in a motorcycle
Many motorcycle shops take your old bike when you buy a new one, and everything above applies: how the valuation works, how it compares with selling yourself, and how the payoff maths works if the bike is still on finance. The same OCPB rules cover motorcycle hire purchase.
The main difference is the size of the numbers. Because bikes cost much less, the gap between a trade-in and a private sale is smaller in baht, and the convenience is often worth it. A motorcycle transfer also needs copies of both parties' house registration. If you would rather try selling it yourself first, see how to sell a used motorcycle in Thailand.
Car or motorcycle, ask for itemised offers from more than one place, confirm your payoff with the lender and read the agreement before you sign. If the numbers show you'd do better selling privately, browse similar listings on Talata and start talking to buyers or sellers when you find a good match.
Why buy or sell a used car on Talata?
If your next car is a used one, Talata brings used car listings from many sellers together in one place. Filter by brand, model, year and price, compare what you see with the showroom's trade-in offer, and contact sellers directly.
If the numbers say selling your old car yourself pays more, list it on Talata with clear photos and the details buyers ask about first: year, mileage, service history and whether it's still on finance. Interested buyers contact you directly, and you can put the money towards your next car. Get started on Talata.
Frequently Asked Questions
Can I trade in a car that isn't paid off yet?
Yes, as long as the trade-in value covers your payoff amount or you can top up the difference. Early in a loan you may owe more than the car is worth, so a top-up is common. Get a written payoff quote first and compare it with at least two valuations.
Can I trade in a car of a different brand?
Yes. Most showrooms and used car dealers take any brand. Valuations can vary a lot because each dealer knows different models best, so get more than one.
Can a foreigner trade in a car in Thailand?
Yes, if the car is registered in your name. You will usually need your passport plus a Certificate of Residence or a work permit in place of a Thai ID card. Check the exact list with the Transport Office, and if the car is on finance, the lender's process applies as usual.
Who pays the transfer fee when I trade in?
There is a Department of Land Transport fee as with any transfer: an application fee, a transfer fee and stamp duty based on the car's assessed value. If nothing is agreed, section 457 of the Civil and Commercial Code says the costs of a sale contract are shared equally between buyer and seller. Dealers usually handle the transfer, so write down who pays in the agreement.
How long does the ownership transfer take after a trade-in?
It depends on whether the car is on finance. If you hold the registration book, the dealer can file the transfer straight away. If not, the lender has to release the book after payoff, which can take around 15 business days at some banks.
Is a car that came in as a trade-in a good buy?
A trade-in car is not automatically better or worse than any other used car. Some come with a complete service history because the previous owner prepared it for the valuation. Inspect it with the same used car checklist you would use for any other car.
Will I get a good trade-in price for an EV?
Used EV prices move with new EV prices and battery condition, so they are harder to predict than petrol cars. Before trading in, ask a service centre for a battery health report and compare listings of the same model before accepting an offer.
