IMO, backdate value depends upon the quality of the build. I also think a high quality build is a pricey proposition. Selling a $50,000 dollar build for $50250 is not much of an ROI. To me the ability to command premium money is in the motor; more power, more desirable, more dollars! I think the recent sales show that backdates with power sell!

As far as the short hoods or impact bumper cars commanding a premium in the future this is a tougher call. There are some limited edition models that currently are selling at a high value such as 89 speedsters, 88 club sport models, 74 euro carrera, 3.0 euro carrera and recently the 74 USA carrera. In Europe, 76-77 Series 1 turbos have also become a desirable model. I suspect these values will carry into the future.

Concerning stock cars; although I do not have the exact numbers I believe the 1983 through 1989 model years represented the highest production output for a Porsche aircooled model line. Given the sturdy nature of the car this should assure many very nice survivors into the future.
