you cant really tell by th mileage. it really depends on how well the car was taken care of and if it was beaten on. i had 250k+ miles on mine and it was still ruuning like new and it was the original motor, it would still be running but it was involved in a hit and run totaling it. you should do a car fax b4 you buy and used car. i also raced it all most every week a couple of days
