I've seen an '84 633CSi for sale in Freehold, NJ. This car is a fantastic parts car, good project car. Has rust around rear wheels, interior is just short of shot, but definitely workable. Car starts right up. I did'nt take very close look but I had to stop 'cause he's only asking $2,500. I don't know the guy, can't vouch for him, but if anyone's interested, I'll get more info.
