Ok friends, I'm very very close to purchasing a local 1979 300SD. No rust, good body. Good interior. All happy and working. Great docs.

Minor details in question:

Cruise control doesn't work... speed decreases when you let go of the switch. If you hold it, speed stays. Easy to find/replace the part?

Tachometer doesn't work... easy find/replace?

Sunroof works, but is quite slow to close. Is that normal?

A few brake hoses that need replacing and driveshaft cover has a small crack. No shaking though.

Rear window doesn't work. Panel was off, so owner was in progress. What's the worst case on a window motor/switch?

Will post pics when I get. :-)))
