I'm considering saving a 1970 220 D/8 (115.110) from the unkind fate of sitting to rot under my father's barn. Its a neat old car, not too much rust, etc. The engine was rebult in 2001, after which my father drove it for a year or so. Its been sitting ever since.

I rescued it about 2 months ago and having been driving it ever since. I've replaced the leaking fuel line, replaced the belts, and had the oil changed. Shifting from 2nd to 3rd has become an ordeal, so I took it to a guy who works on old mercedes. He tells me I need a new clutch, and that it will run $1300!

So, #1 is it worth trying to save the car, #2 what should a new clutch cost me, and #3 what else should I have checked out?

Many thanks for the help!
