I am asking this question because most cars prices are either expensive or cheaper depending on the mileage , how easy is it to calculate the mileage is it possible for an ordinary buyer to walk up to a car dealer show room and calculate the mileage himself or you just have to take what the car dealer says , is it computer the normal laptop used in calculating it or how? please advises i needed not abuses cause i know some people are on here that wake up from a nightmare and would want to shake it off by cursing or abusing other people ,,Thanks good people please reply

Rough estimate: No of years X 12,000Miles

Thanks KOMBE but i need deep information about it you said years times 12000 miles , what if the buyer purchases it and doesn't use it regularly until like after a year before selling it and another person purchases his same day and uses it regularly or over regularly and wanted to sell it after a year won't it read same miles with your own explanation

What he meant is an average car does 12000 miles a year. A ten year old car is supposed to have about 120k miles. If you now see 180k or 200k miles on a ten year old car it is high milage. Similarly, if a ten year old car has 50k miles, it is posible but suspicious.
I will rather go for a high milage but well maintained instead of adjusted or suspicious low milage.
Car is about maintenance, my close friend has a honda currently at 270k miles no shortage of oil, no smoke.
There is no computer known to me that determines car mileage.
