The Venom GT is a much larger vehicle than the Elise. If there are ever any comparison shots of the two, you would see this.
If one is of the opinion that this is a strictly bolt-on job, one is wrong. I've seen it in the flesh and seen it run. Given all of the modifications done unto the car, the fit and finish are excellent.
If the black one seems strange to you, it is probably because that is the prototype vehicle. The one at CC Houston was the first production vehicle, not the mule.
Upkeep should be cheaper than just about everything north of 150K.
