I am new to the site and am looking for some help. I am getting ready to buy a 1994 2 owner Eldorado with 47,000 miles on it. The car is in showroom condition. The problem is it has a slight oil leak. The owner says about .5 quarts every 6 months. He seems to believe it is the rear main seal. Could anyone tell me the worst case scenario, such as if the leak is from somewhere else. If it is the rear main seal, what kind of cost am I looking at? I am buying it for $3500. If the source of the leak is something else, what would be my cost of repairing at its worst?
Thanks ahead of time for your help.
