I bought my E30 in June 2001. So far I haven't done a whole lot to it because of time and money constraints. My first order of business is restoring the car to perfect condition. I just installed brand new OEM foglights and a leather shift boot cover last week. Now I just need to have the front end re-painted and replace the cracked headlights and she'll be pretty much mint.
It was involved in a rear end collusion in May 2002. The rear bumper had to be refabricated and the head of the motor had to be rebuilt as a rocker arm broke. I had the timing belt changed at the same time. She's now back in great condition and is running smoother than ever.
