The short answer
How trade-in and private sale compare
| Trade-in | Private sale | |
|---|---|---|
| Price you get | Lower; the dealer needs room to resell | Usually higher |
| Time and effort | One conversation | Photos, listing, messages, viewings, test drives |
| Timing | Same day you buy | Days to weeks, depending on the car |
| Risk | Low; the dealer takes the car as it is | Tyre-kickers, no-shows, payment scams |
| Paperwork | The dealer handles most of it | You notify NZTA and sort the WOF question |
| Best for | Older cars, cars with faults, tight timing | Popular, well-kept cars with service history |
Why is a trade-in offer lower?
Because the dealer has to resell your car at a profit. That means reconditioning it, paying for a WOF, covering consumer law obligations when they sell it on, and carrying the risk it sits on the yard.
That isn't a rip-off. It's the price of handing all of that to someone else. The question is whether the gap is bigger than what your time and effort are worth.
What you must do when you sell privately
Selling privately means the legal bits are on you.
- The WOF. A buyer can insist the WOF is less than one month old. If they accept an older one, get that in writing.
- No current WOF. Advertise it "as is, where is", and get the buyer's written agreement that they won't drive it except to get it repaired or inspected.
- Money owing. Any finance secured on the car needs to be cleared from the sale price.
- Rego and RUC. Licensing should be current, and RUC up to date if it's a diesel or EV.
- Tell NZTA. You and the buyer must both notify NZTA of the sale straight away. It can be done online.

Buying and selling at the same time?
Tell us what you're after and what you've got now. A carfinder will find 3 cars that fit, and help you sell or trade in your current one.
How to get more for your car, either way
- Find the service records and receipts. Proof of history is worth money.
- Clean it properly. First impressions move the number.
- Fix the cheap things: a blown bulb, a worn wiper.
- Get a valuation range first, so you know a fair offer when you see one. The fair price guide shows how.
- For a trade-in, get more than one offer.
The short version
- Private sale: usually more money, more effort
- Trade-in: less money, much less effort, same-day timing
- Negotiate the new car's price before you mention the trade-in
- Selling privately? Sort the WOF, money owing and NZTA notice
Common questions
Is it better to trade in or sell privately in NZ?
For a popular, well-kept car with time to sell, a private sale usually gets more. For an older car, one with faults, or tight timing, a trade-in is often the better deal overall.
Does my car need a WOF to sell it?
Not legally, but a buyer can insist on one less than a month old. Without a current WOF, sell it "as is, where is" and get the buyer's written agreement not to drive it.
Can I sell a car with money owing on it?
Yes, but the debt needs to be cleared from the sale. Buyers can check the PPSR, and most will walk away if it isn't sorted.
What do I have to tell NZTA when I sell?
That you've sold the vehicle, and who to. Do it straight away, online or at an agent. The buyer has to notify NZTA too.
Can a carfinder help with my current car?
Yes. Your carfinder can help you sell or trade in your current car, so you're not juggling two jobs at once.
