You can rice anything.

You can have a civic that's not rice, and a mustang that is.

Normally it's imports, and not normally domestic. When it is domestic it's typically the slow, small cars, once they're in an affordable price range - cavalier, focus, etc.

Almost anything tacky, gaudy, or overdone is rice-esque: big body kits, coffee cans, giant spoilers, vinyls/stickers, etc.
