Added alloy rims; K&N air filter; Performance exhaust; Kenwood Excelsior stereo with 10 disk changer; Polk Audio speakers. Bought it in 1998 with 51K miles; now it has 135K. Car was broken in to, and later hit where it was parked, destroying left side nose to tail. But, I keep putting her back together, good as new. I love my Z!
