Cars of SEMA 2015. SEMA is coming up here soon at the end of the year. We thought we’d take a look back at some of the hottest cars that were featured at last year so. If you’ve never been you’ve got to go. SEMA is full of some of the sexiest models hottest cars racing off-road vehicles and more. It’s one of our favorite events that has a well-rounded balance of everything you could ever like in the world of Auto Sports. In fact the show is so large it will take you 3 days to go through all of the convention halls and still you’ll probably missed a lot of great things.
