I am buying a Used car (1996 MERCEDES-BENZ C280, 116,500 mi). When I took it to FireStone to do a "Vehicle Inspection", it came out that there is pretty bad oil leak from engine. They are NOT sure as to where exactly the leak is happening. Unfortunately, Firestone said they cannot run a complete diagnostics to find the exact leak.
I just want to know how serious the problem is and roughly how much will it take to fix it (ballpark figure $$). Accordingly I will decide to buy the vehicle or NOT.
