How to value a modified SC?
 

In the Spring of 2005 I purchased a 1980 911sc. The car had two owners prior to me. The first held it for 23 years and lavished it with love. It was treated to niceties such as a complete motor rebuild by John Walker with new Mahled P&C’s, Oil pump, etc… second owner had the car a very short time and then I came along.

a pic would help as these items are great but are they tastefully installed and what does the over package look like.

thanks ed

$20K. give or take... Depressed sellers market..The specs read nice, but a picture backs up the claim. Visual issues like Paint and interior can be a doom.. Decent quality repaints can be what, $5k? How bads the interior upholstery?

$290k seems high for an SC, no matter what it has had done to it. Then add paint and you are at $24-27000. No one will pay that much for an SC when good original ones are floating around in the low teens.

290K? Yikes.. that would be high for an SC.. maybe market correct for a '73RS though ;)

$20k :) If I had $290K to buy a car, I'd buy a low miles Ford GT for $130k and put the rest into a lost week in Vegas....
