What the Cannes Film Festival is to cinema and Paris Fashion Week is to couture; SEMA is that, and then some, to the automotive aftermarket. With more than 2,000 exhibitors and 125,000 attendees in over a million square feet of space, it's a four-day gauntlet of all things car. But because most of you readers can't attend-it's an industry only trade show-we've acted as walking proxies, traversing damn near every inch of the show floor, to bring you back the 45 hottest aspects-and we mean ass-pecs-of the show. And believe us, it wasn't easy. After a whole lot of walking, photographing, drinking and deep consideration we narrowed it down to the top 10 wheels and tires, parts, models, and of course, our pick for the top 15 cars. This time what happened in Vegas didn't stay in Vegas-with the exception of a large chunk of what little cash (and liver) we brought.
