mmm i dont know they didnt give me any service records the car runs great but the check engine light comes on and it throws code po421

These cars will run strong for upwards of 200k as long as you keep up with maintenance, that code is a cat code so it is a good possibility you will need to replace at least one of your catylitic converters. Good thing is is that doesnt effect the way your motor runs but it will need to be fixed before an emissions test. Keep up on maintenance, let it warm up completely before driving it hard at all (wait till oil temp is at first tick mark) Oh yea, be ready to spend 5k if the turbos blow.... other than that enjoy!!
