When DH & I have done it we've always been in the back of a car, but we always ask for seats near the screen, so we don't care. Also, if you give your camera to the waitress, you can get the cutest pictures from the back of the car in all sorts of poses (on the trunk, so to speak), whereas you're sort of limited to one cute pose in the front.
I don't even remember the people in the front seats, to be honest. The preview reel will keep you so occupied you won't notice them.
