so to the origional poster - as to what E30's to stay away from I think steer clear of EJ red's car, even if he has a 1.7 honda motor swaped in to make it bullet proof.
One your gonna laughed at and two, I don't think the work being done on it was ever done by someone with a clue. Just cause they have the same bolt pattern dones't put them in the same class.
All other E30's are pretty much priced according to what has and well need to be done. The cheaper the car the more work you may have to do.
