I was at the Houston auction as well. (1985 perhaps?) I didn't know the car was there until I heard it start up. The venue wasn't that big and the sound just totally engulfed the structure. I was totally blown away when it entered the arena and I consider myself lucky to have been there. IMO, this car is in the stratosphere of musclecars right along with the Supersnake and some others.
Has it ever been dynoed? Are there any published comments from Joel Rosen regarding the car?
