You can take a Cayenne and put a TecArt package and it makes it look great. But the entire package costs around $30K. The Brabus store in the Newport Beach area off the 405 does it. I saw a black Cayenne Turbo that had the entire package at the Brabus store, started drooling.
My dad went from a 4.6is to a Cayenne Turbo and loved it. The speed in that thing was ridiculous, I actually didn't feel too safe driving it in case I pushed too hard on the gas.
