This looks like the place! OK I always wanted a '91 318is and I just bought one for $500. I haven't got it home yet, but it will be on the tow truck this weekend.
It starts but won't idle. The PO said a spark plug backed out and it stalled. They replaced the plug and that didn't help. I think it needs a major tune up, or maybe there is a valve train problem. Nevertheless the PO didn't really know her car and I gladly took it off her hands. Great body (hers too) silver, no wrecks, decent interior (seats not ripped) - a diamond in the rough.
But glad to find this site. Any things I should look for I would sure appreciate some tips.
