As soon as it hits the 50k , the engine will start to loose it's compression, the bumper will fall off, the ecu will burn into crisp, the leather will start to crack, the interior will start to smell like an old fart and the car will turn on by itself and run you over . It's a scary feeling!!
Relax enjoy your Z
Z at 50K is like a mature chick the older she get the better she is on the bed!
