Oh, MAN, that Fawn interior...
I've been trying to get the interior in my '66 SS painted the correct color and gloss of Dark Fawn for 4 years. It's been painted twice now and it still isn't correct. That's the ONLY thing preventing me from final assembly of the car.
This car is way cool, but as Tony said, the engine bay needs some changes to look more period correct. And the steering column needs to be disassembled and the shifter nub removed to appear original.
