At first I thought something was wrong with the car, but there was a 69 Camaro on the rack next to me and the measurements were the same. Guess they are all like that.
BTW, I've seen them out the back in every way conceivable, I decided to go the hidden look. Still glad I did. I was partly concerned I would drag anything that showed out the back, and partly wanted it to be hidden... not that there's anything stealthy about this car.
