It's the time of year again. The aftermarket world and manufacturer vehicles collide in the biggest auto show of the year at the 2007 Specialty Equipment Market Association! Thousands of aftermarket product manufacturers annually head to Las Vegas to show their latest product lines to the millions of potential buyers and spectators hailing from all over the world. Aftermarket parts venders, industry executives, OME dealers, auto scribes, you name it.

More importantly to automotive enthusiasts of all genres, SEMA is an annual opportunity for engineers, designers and the like to go all out and come up with extreme creations that would otherwise never make it past the concept drawing. More than 40 automotive manufacturers, including Ford, Chevrolet, and Dodge also take part in the aftermarket extravaganza. Best of all the OE-manufactures step up to the plate of aftermarket with some of the coolest one-of-a-kind designs that might make it to dealer showrooms in the future.

Join Truck Trend on the showroom floor and at Truck Trend's very own Proving Grounds as we take a look at what the aftermarket world has in store for the future.
