When I got it on March 17, 2017 it had a mere 40k miles on it. Since then, I have amassed almost 37k miles behind the wheel. For the vast majority of the time, it’s been trouble free. It has had 3 coils go bad, and some leaking gaskets have been replaced. Other than fluids, that’s all I’ve done to it, well besides put new tires on it. It did eat a set of fronts, but that was fine because I already had the replacements on had as they came off the front of the M3 when it got tires in May of last year.
