Well, there's something to be said for having an actual original COPO car, and with lots of original pieces....
From the firewall back is original metal (aside from quarter panel repair), the interior is original, all the glass is original, the bumpers and trim are original, the dash is original (it still has the cut out in the speaker screen where the cable drive tach was installed), the rear bumper is in great condition and has some push truck marks in it and the push button starter and cut off switch holes are still in the lower left dash panel. The radiator (when he dropped the race engine in Mr. Arnold had the radiator neck changed for better flow) and rad. support is also original along with "frame rails",
Don't most rare cars, COPO Camaros included, by the time they are acquired, come lacking many original components, often needing complete body restorations, and so many already have a CE engine installed, or no engine at all, where the next best thing is finding a date coded, period correct drive train?
We all know original drivetrain and paper work is the most sought after pieces of the puzzle to make the vehicle worth all the money, but in my opinion, not having those things does not change the fact that it is an actual, real deal, COPO Camaro from the factory with a cool story. Like he said, that's why he selling it for 100k less than he thinks it would go for if it were 100% right and restored.
