Each car has to stand on it's own merits. Two cars of the same year, any year, could have values of thousands, maybe 10's of thousands more or less than the other car. It depends on what level of car your looking for. Perfect, driver, DIY project. To ask what a 85 Carrera is worth, just to pick something out of the air, is meaningless. What 85 Carrera? What Color, rust, no rust, stock, very personalized, suspension, drivetrain, electronic glitches, none, etc, etc, on and on. Having spent some time restoring Longhoods, I've become paranoid. Finding one that's as advertised is few and far between. 15 to 20 years ago these cars weren't worth much. And they were repaired as almost valueless cars just to pound around in. If shunted, who cares. Body work to repair the body work, and done properly is VERY expensive. The paint off restorations I'm doing end up in the 3 to 400,000 dollar mark not including the cars. Those numbers bum me out and it takes the fun out of it for me.
I've driven SC's and 84 to 89 Carrera's. I just can't get into them. They're like lead sleds. Yuck. I think my Porsche days are numbered.
