There are two things that we've come to count on happening each year, right around the middle of the Fall season. First, in most parts of the US, temperatures get a little chillier (especially after dark). And second, the automotive industry's "trade show season" kicks off, with the legendary SEMA Show in Las Vegas, Nevada. We look forward to attending SEMA each year, as the show really is the "place to be" if you're a hard-core custom-car and/or high-performance car nut. Editor Steve Turner, and Senior Tech Editor, KJ Jones, are attending SEMA 2013, to see what type of hot, new goodies are coming out for new for Mustangs. Here's a behind-the-scenes look at a few of the things that were taking place inside the show on Monday.
