Knowing how to accurately value a used car is the key to getting a good deal. Overpaying is one of the most common mistakes buyers make. Here is how to work out what a car is really worth before you commit.
Start with trusted online valuation tools. Parkers, What Car?, and Auto Trader all offer free valuations based on your registration number or the car's make, model, age, and mileage. These tools give you a trade price (what a dealer would pay) and a retail price (what you would pay a dealer). Private sale values sit somewhere in between. Use these figures as your baseline.
Look at what similar cars are actually being advertised for. Check Auto Trader, Facebook Marketplace, and eBay for cars of the same make, model, age, engine, and mileage. Pay attention to cars that have been listed for a while, as they may be overpriced. If a car has been on sale for more than three weeks, the seller may be open to offers. Look at sold listings on eBay to see what people actually paid, not just what sellers are asking.
Valuation tools give you an average figure, but individual cars vary. A car with full service history, good tyres, a clean MOT, and a tidy interior is worth more than the average. A car with patchy history, dents, worn tyres, and an upcoming MOT is worth less. Be honest about the condition and adjust your offer accordingly. A £2,000 car in poor condition might only be worth £1,500.
Mileage has a big impact on value, but it is not the only factor. A 10-year-old car with 60,000 miles is worth more than the same car with 120,000 miles, but a 120,000-mile car with full motorway history and good maintenance could be a better buy than a 60,000-mile car that has been used for short trips. The condition matters more than the number on the clock.
A car with a clean MOT history is worth more than one with repeated failures. If the MOT history shows consistent issues with corrosion, suspension, or brakes, that suggests the car has not been well maintained and will likely need work soon. Use these issues as leverage when negotiating the price.
If the car needs tyres, a timing belt, or has an advisory on the MOT that will need addressing, subtract the cost of those repairs from your offer. A car priced at £2,000 that needs £400 of work is really a £1,600 car. Remember to add your labour if you are paying a garage to do the work.
