I've taken my Firebird every year since 2003 and went a few years before that in my daily driver. There's a lot going on, it's like a 16 mile block party with cars.

Be sure your car is up to hours of traffic jams if you do the Royal Oak stretch, you see overheated cars every year that couldn't handle the stop-and-go. It's more open on the north end, and there is a freeway (I-696) you can hop on for a little more cooling.
