The Japanese aren't as fond of two seater cars as Americans are, the culture deems them impractical or wasteful.

The solution, add a set of backseats that are too small to actually fit a person in. RX-7's, CRX's, 300ZX's, and a few other cars are like this.

I use my 2+2's for additional storage space. They keep stuff from flying forward out of the hatch area too, creating a little trunk area. I'd imagine it would be the same for a CRX.
