hello all i have a 1984 300sd with a grease car kit bought the car with it a while back car is rusted but reliable runs great need a few things done but i saw a 1992 300sd i love the body the engine was rebuilt 7 years go the owner states, but it sounds loud he says that it has dirty injectors
and also the heater and ac dont work but the blower works
i really like the body style also since the motor was rebuilt makes me really interested im going to ask if he has paperwork of the rebuilt if not then i wont be interested also my concern is the ac/ heat unit what would i be looking at in trying to repair that?
