What does the comparison show?
Make, model, year, fuel, engine size, emissions, tax and MOT status, how many MOT tests were failed, the advisories at the last test, the last recorded mileage and the average miles per year.
Does it tell me which car to buy?
No. It only highlights where one car is lower or later on a measure that is usually better, such as emissions or MOT failures. A free comparison cannot see finance, write-off or stolen records, so run a full history check on the car you choose.
