Car sex...not my favorite and would probably never try it again. I've been in the back seat and since I have really long legs and he was about 6' it wasn't comfortable or romantic. Redlemon suggest front seat...may work, but again I can imagine my legs would be hurt by sliding between the seat and the door and the middle console.
I say go to a place that is quiet and secluded. Get out of the car and do it on the hood. Still car sex, but a lot more room
