Before you sell a car, part-exchange it or insure it, you need a number. The trouble is that there is no single number: the same car has several values at once, and the gap between the highest and the lowest is usually thousands.
Here is how those values differ, what actually moves them, how to find out where your car sits, and how to use the figure once you have it.
Your car has four different values
Start here, because almost every argument about what a car is worth comes from two people quoting different ones:
- Trade-in value. What a dealer will allow against your next car. It is the lowest of the four, because the dealer has to recondition and resell it.
- Instant cash offer. What an online buyer or a dealer will pay outright, sight unseen, subject to inspection. Usually close to trade-in, sometimes a little above.
- Private party value. What another individual will pay. Typically the highest you can realistically get, at the cost of advertising the car, meeting strangers and handling the paperwork yourself.
- Dealer retail. What the same car costs on a forecourt with a warranty behind it. You will never get this for your own car - it includes the dealer's costs and margin.
On an ordinary five-year-old family car, the spread between trade-in and private sale is often 10 to 20 per cent of the value. That difference is what you are paid for doing the work yourself.
What actually moves the number
Seven things do most of the work, in roughly this order:
- Age and depreciation. A new car loses around a fifth of its value in the first year and roughly 40 per cent over three. The curve flattens after that, which is why older cars lose value more slowly in absolute terms.
- Mileage. Around 12,000 to 15,000 miles a year is treated as normal. Significantly above that costs you; significantly below adds, though not as much as owners expect.
- Condition, mechanical and cosmetic. Kerbed wheels, worn tyres, a warning light on the dash and a scruffy interior all come straight off the offer, because they are the first things a buyer or appraiser sees.
- History. A clean title and a documented service record support the price. An accident on record, a salvage or rebuilt brand, or an inconsistent mileage history reduce it sharply, and no amount of polishing changes that.
- Make and model. Some models hold value far better than others. It is a property of the model, not of your car, and there is nothing to be done about it except know where you stand.
- Local demand. The same car is worth more in one region than another - all-wheel drive in a snowy state, a convertible in a warm one, a pickup where people tow things.
- Timing. Convertibles sell better in spring, four-wheel drive before winter, and the wider market moves with fuel prices and interest rates.
How to find out what your car is worth
Six steps, and the order matters:
- Get the exact specification. Year, trim, engine, drivetrain, options and mileage. A valuation for the wrong trim is worthless, so use the VIN rather than guessing.
- Run the valuation guides. Kelley Blue Book, Edmunds and J.D. Power (formerly NADA Guides) will each give you trade-in, private party and retail figures. Note all three.
- Get at least two instant cash offers. Online buyers and dealer buying programmes will quote from the VIN and mileage in minutes. This is your floor - the number you know you can get without effort.
- Check live listings. Search your own year, trim and mileage within a reasonable distance and see what similar cars are actually advertised for. Asking prices are not sale prices, but they show the ceiling.
- Pull the history report. Whatever is on it will come up during the sale. Better you see it first than have a buyer produce it at the kerb.
- Take dealer appraisals. Visit two or three. Free, quick, and they give you real offers rather than estimates.
What raises the price, and what does not
Small amounts of effort pay disproportionately here - and some things owners believe in do not pay at all:
- Worth doing: clean it properly. A professional detail costs little against what it adds, because condition is judged in the first thirty seconds.
- Worth doing: find the paperwork. Service invoices, the owner's manual and the second key are all worth real money. A missing second key alone can cost you a few hundred.
- Worth doing: fix the small things. A warning light, a blown bulb, a worn wiper. Each one invites the buyer to wonder what else was ignored.
- Usually not worth it: major repairs. You rarely recover the cost of a new clutch or a timing belt in the price. Disclose it and price accordingly instead.
- Not worth it: modifications. Aftermarket wheels, exhausts and tuning narrow the pool of buyers and usually reduce the value rather than raise it. Refitting the standard parts, if you have them, is often worth more.
- Worth nothing at all: what you paid. What you spent, what you owe on it and what it means to you have no bearing on what anyone will pay.
Using the trade-in properly
If you are part-exchanging, five rules turn the trade-in from a weak point into leverage:
- Know your floor before you go. Walk in with an instant cash offer in your pocket. Any dealer offer below it is simply declined.
- Negotiate the two deals separately. Settle the price of the car you are buying first, then discuss the trade. Combining them is how a good trade-in allowance hides a bad purchase price.
- Ask for the numbers in writing. Price of the new car, allowance for yours, and the difference. If a dealer will only discuss the monthly payment, you cannot see which number moved.
- Get more than one appraisal. Dealers value cars differently depending on what they need on the lot that month.
- Be willing to leave. The trade-in is optional. You can always sell privately afterwards, and dealers know it.
One thing that genuinely favours the trade-in: in most US states you pay sales tax only on the difference between the new car's price and the trade allowance. On an expensive car that saving can be worth more than the extra a private sale would have brought.
The bottom line
Your car does not have a value - it has a range, and where you land in it depends on how much of the work you are prepared to do yourself. Trade-in is the fastest and cheapest; a private sale is the slowest and the most profitable.
Find the specification by VIN, collect the three guide figures, get two cash offers as a floor and look at live listings for the ceiling. Then decide which end of the range is worth your time.
