"It seems like every other classic car has jumped in value except for our Coupes."
There are plenty of collector cars that suffer from rust, yet they are restored without fear and quite a bit of gusto, and maintain their value. Unfortunately, in terms of public perception, BMWs fall into the aftermarket tuner world category, just like VWs. I believe this perception, along with owner self-denegration in some cases, devalues coupes. How can a car that is consistently cited as a great design remain stagnant in the collector car market?
I'm about to embark on a partial restoration of my '81 911SC—glass out, bare metal respray w/ Glasurit, backdated exhaust, and rebuilt, not upgraded, brakes. I have the opportunity to fundamentally alter this car, but I won't. I could make it a tribute car, I won't. In fact, its a ROW car and I'm going to do my best to return it to a 911SC that rolled off the factory floor and lived its life in Germany. FYI—I'm a museum exhibit designer, used to working with, in many cases, one-of-a-kind unalterable artifacts. I guess I see my coupe as drivable artifact...
