What's so great about it? The only thing that's Rolls Royce is the grille/front fascia and the fact that it has suicide doors...I find it just as dumb as when someone puts a Cadillac Escalade grille on a Silverado. Cadillac DOES make a pickup truck thingy, the EXT! I see so many Silverado's with Escalade grilles! For the price of a "Cadillac Silverado" body kit couldn't you just buy an EXT (maybe a slightly preowned one?).
Now this would be cool if it was an ACTUAL Rolls Royce prototype or something...
