1978 Mercedes Benz 450SL has a lot going for it. It has had a new catalytic converter and pipes installed recently along with a new battery, new, black cloth convertible top and new brakes. The tires are almost new as well. It also has the hard top stand and cover. Everything works on this SL as it should. The A/C does work but needs a shot of R12 or it needs to be converted to 134A. With 135,000 miles, this 450Sl is just broken in!
