Local market will ultimately determine the price.

I would not pay a dime over $2k.

The water inside is most troubling to me. Rust? Leaking sunroof?

I agree that a new OVP may solve most of the electrical issues, but if it is that simple, why hasn't the owner done that?

The CC issue sounds like a bad OVP _and_ a flaky amplifier. Re-flowing all the solder on the printed circuit board probably will fix that.

All that said, I think that engine is probably the most reliable in any MB diesel from 1986 through 1999. Not the biggest / most powerful, but extremely well put together and durable, great economy too. The only real weakness is the vacuum control of the turbo waste-gate, which may be part of your sluggishness issue.
