I stumbled across a pretty nice 1979 911sc with the 3.0 engine & 5 speed. It needs a headliner and the original paint is in bad shape. No rust issues and a little over 100k miles on it. interior is decent. Runs and drives great. Anyone have an idea of what it might be worth? I have been looking on line at them and the prices are all over the place. I am very close to buying it, I just dont know much about these cars.
