What would a fair price be for this car?

1980 Mercedes 450 SEL. Last production year for the 450. 138,000 total miles. 2nd owner. Dealer maintained. Totally straight. No rust. Never in accident. Car lived in Los Angeles. Interior needs new seat covers and dash cover. Front and rear glass need to be re-sealed. Car engine runs really well. Transmission should be rebuilt. 2nd gear slips if you step on it. The entire aircondintioning system was just relpaced by a dealer prior to parking. Perfect as a project or parts car.

Looking for the "fair" price range.

Any ideas?
