some of the crx's had back seats.they were small and really unconventional but they had them in japan.i think it would be nice.hell sometimes i have to sit on the cargo are in friends crx's. basically a seat any ways just a little unstable.i think if there selling"back seat kits" it would be a good addition to the people who want small compact sports cars but who have the friend who drinks to much and needs a ride every once a while.i think its a good idea.
