Help w/Buying 560 SEL 1989

[moohampshire]

I am buying the above car and it has 70K miles on it. I bought it through ebay and I have had a mecahnic look at the car in Indiana. He tells me it is misfiring in one cylinder and the owner tells me he has seen this before and it is the ignition coil. The owner tells me the both front power seats do not work. Are they on one fuse or one motor for both. It sounds funny they are both not working. The power antenna doesn't work but I have replaced them on my volvo- no problem.

With the blower motor not working he (mechanic) couldn't tell me if the A/C was working. He did say that I would have to change out the R-12 to 134. Most if not all of this work I can do as I have always had less than new cars.

Any help would be greatly appreciated as I join the ranks of Mercedes owners
