[Rawknees'Turbo]

I don't see how the tail and front valance would be a "killer" except to the most uniformed buyers (maybe that's who's primarily spending the big $$$ for these cars, however), as while not cheap, they are easy fixes.

Myench, I don't know a cost total to give you, but on the front you would need to find a year appropriate valance (the one with the fog light cutouts) and a 930 front spoiler strip (the black plastic, wrap around piece that mates to the front fender flares) and on the rear, you would need to find a complete, 1978-1989 Turbo engine deck lid and tail (it looks like the DP tail uses the original rubber lip, so you wouldn't need to buy that if the one on the car is in good shape) . . . then the parts would have to be prepped and painted to match the rest of the car.

So while the process to convert those sections back to stock is relatively simple, the costs would add up in a hurry - especially if paying someone else to do the fitting, painting and install work.

To get an idea of what it would take to buy the parts, you could check eBay "sold listings" - an excellent way to judge what the parts are worth.
