These are moderately unique cars, though here in the US they don't seem to command the premium they get overseas, especially compared to the lesser US '74-77 Carrera 2.7CIS.
Rick Cabell is primarily responsible for mine. He originally imported it in '84 and got it federalized, sold it and then repurchased it in 2001. He then started a multi-year freshening, whereby he repainted it, installed an RS carpet kit and deleted some insulation, and rebuilt the engine to 3.0RS-MFI specs. That is the way Porsche should have built this car originally, although the 3.0CIS was also a nice configuration.
This car never had a sunroof or A/C, but has the factory sport seats, LSD and whale-tail. Consequently relatively light at 2,425 pounds with 3/4 tank but no driver.
Would love to touch base with the owners of the two continental orange cars here in the US. John, you've done a great job with that car. Best of luck to you on the sale.
