I have recently started looking for a GT to buy and have limited knowledge about them. I am currently at the Mecum Auto Auction in Kississmee, Fl. There is a 2005, white w/ blue stripes, 3 options (no painted calipers), with 577 miles which will be auctioned off this weekend. I looked it over carefully today and could only find one small ding just above the rocker panel. But my question is about the rear bumper. There is about a 2 inch gap, which looks like it was designed that way. I just thought it was odd (I've never actually seen one in person) looking. Is this normal and what is the purpose?
