Well, I checked it out the other day and had it inspected. This is actually the first time i've driven an e30 and I really liked it. However, the inspection turned up quite a few issues, all of which seemed to be due to regular wear rather than abuse. Here's the list:
Fuel pump - functioning, but it's loud and probably needs to be replaced.
Windshield Chip - apparently large enough to be ticketable, also liable to grow.
Front struts - old, need replacing.
Fan belts, antenna grommet, power steering hoses, oil pan gasket, differential side axle seals, brake pad wear sensors, rear sway bar bushings, lower A arm bushings, front brake hoses, and the driveshaft jurid coupler - all need replacing.
AC system - blows cool, not cold. Mechanic wasn't sure what the problem was, but thought it could be expensive.
With all this taken into account, the mechanic said he wouldn't pay more than $2000, which I agree with. However, the seller said he wouldn't go less than $3000 and would prefer to work on it himself than sell it now. That definitely seems high, but it's hard to let this oppurtunity go, considering how uncommon these things seem to be in my area.
