it is all in how the back opens. if the glass goes up with the trunk, then you have a hatchback. more examples would be a 3000gt, 240sx fastback, toyota celica. i can understand the confusion. i don't know how the trunk opens on the SLR, so i can't really help you with that. IMO, the cars i listed as well as the corvette are fastbacks, not hatchbacks. please someone correct me if i'm wrong
