Haha, I don't see the point either!!!
I don't tend to see the point in Pimp My Rides mods either in most cases. I mean, yeah, TV's are great, but do you really need them in every car in big 30 inch screens?etc?
A good sound system? Great! But, using up the back seats for what was a massive subwoofer on one episode?...er...haha
Some of the stuff they do is kewl though.
