160 something k on drivetrain...
never any internal engine trouble but it did get driven correctly

I was good with maintenance too actually because I had one of those aftermarket warranties everyone got screwed by witch mandated proof of oil changes..
had a torn intake boot once upon a time, and wires ripped off the 02 sensor from mushroom hunting.. only problems..
I have one of those code scanner tools for the bmw before obd2 also if anyone is interested..
1.8l dohc i4 m42.... badass little engine
