So from what I have discovered, these cars have bottomed out as far as depreciation goes. SO- if I was to find a pristine, well maintained example and pay the correct amount, I should be able to have fun, figure a couple thousand a year in maintenance worst case, and then sell for the same.
I also saw a guy on an E30 forum with an AMAZING sales thread on a 4-door E30 with some pretty sweet work on it. Its already got a deposit on it, but man, if that deal falls apart, it seems like a smokin deal for me.
