I saw an Alpine white 71 Hemicuda convertible with a black top at a car show in Grand Junction, CO. Yes, it was the real deal. It was stunning. Oh yeah, the owner drove it to the show. This was around 1995.
I found some info on the car I saw.
The Brothers Collection GW3 Sno-White car has a TorqueFlite and 3.23 gears. This car was originally exported to France and I believe this is the only one produced with the black Billboard stripes. This is the last Hemi Cuda convertible that was produced. http://www.yenko.net/ubbthreads/ubbthreads.php/topics/635896/mcacn-15-photos-by-mrays
