Very solid car IIRC.
$36 was very good 3 years ago.
Given the rise in value of solid E9s, I think it's worth a good $42k now. Just needs new seat covers to match the rears. And of course that rear bumper fixed.
Not too many cars out there where you can buy it, not do anything to it except drive it, and sell it for more money.
Good car to buy. Interesting that it has sub-'73 front overriders (which I prefer BTW) and no front side markers.
