I've located a 560SL that hasn't started in a while. The owner left it on the car lot of a friend and hasn't returned. (he bought a 1998 SL from the guy) It's in good shape, no rust, complete with hard top. But it hasn't started in a while (6 mo - 1 yr) I can probably get it for 5K from the guy. It has 123,000 miles.<br> <br> Should I buy it? I'm good working on engines (had a few SAABs) and enjoy tinkering. What would be my first thing (besides the battery) to investigate so I can start this beast?
