I almost made 314K kms on my 325i auto. trans. car, but the head gasket went and so did the car. Since the body was starting to bloom, I decided against fixing it. Too bad we live in a rust belt, otherwise it would have been nice to keep driving the E36....
My buddy mentioned he knew someone with over 500K kms on his E36, and the same person was told by his brother in law that one of his clients has a 1980's Porsche 911 that just turned over 1 million kms; I believe it's going to be featured in an upcoming edition of Excellence magazine.
