Since someone metioned it, I make a topic for it razz
In all seriousness, SEMA is probably the biggest event in the North American Automotive industry (that and NAIAS). The event has grown so big that the convention hall where SEMA is held isn't big enough, and tent's needed to be set up outside the buildings ( that's 2 million sq feet of cars). The sad part is it isn't open to the public, which totally sucks.
Two big hit's of the 2007 SEMA show were the Chrysler Concept 'Cuda and the Audi APR8.
The Concept Cuda is a custom built with the body structure and internals coming from the Charger SRT-8. The Car has such acclaim that some wonder if Chrysler will actually build it Concept Cuda
The APR R8 is a tuned version of the R8. Not much is known about the car, but many hope that the car posses a V10 APR R8
