Well, um.
I think I'm the fifth owner, I've had my 325 for thirteen months. I had the valvetrain rebuilt after the last owner let the timing belt go slack. Past that all I've done (besides replacement OEM parts) is had it re-painted Luxorbeige Metallic, removed the pinstripe, and had the aluminum trim blacked out; I put in a Pioneer DEH-P3600 head, Infininty Reference component and 6.5" speakers, a cheap subwoofer and an MTX amplifier. I wish I could do more, but students have no money.
Got to save for the E36 anyway.
