i am looking at purchasing a 99 z3 with 230k and bad head gasket. the owner is telling me that it is a 2.5 . the question is how do i tell if it is a 2.5 or 2.8? would it be in the vin, any visual differences, etc??
i am going to look at the car tonight. it doesnt have the numbers on the trunk lid.
so the sooner the better with an answer.
thank you
