The world's biggest automobile aftermarket show is on right now in Las Vegas, Nevada (where else?) celebrating the art of customising, tuning and modifying standard cars until their own mothers wouldn't recognise them.

The Specialty Equipment Marketing Association show attracts the top custom builders in the United States - often funded by the manufacturers themselves, who don't want to lose out on an important segment of the market - competing against each other to see who can produce the wildest show cars.

Settle back and enjoy our gallery of the best of the best from SEMA 2012.
