I'm looking at a 1972 350SL, 75,000 miles, most of which were driven in the first few years, then driven about 1000 miles a year when not in indoor storage (Buffalo, NY Area). They are asking $10,000. Anything special to look at on these cars? It's close to what I can afford, but is it better than an 86 560SL with over 125,000 miles? Any outstanding mechanical issues? What would you offer for a price?
