A sleeper hummm........ A late model ('75-'76) four door Valiant......dog sh*t brown with primer & rust spots, ripped tan interior, aftermarket wood grain molding, and full hubcaps on white wall tires. The kicker.....one of those new 440 small blocks, 5 or 6 speed manual on the floor disgusted (sorry for the butchering of that word) as a 3 speed. The only evidence would be duel exhaust, wider wheels in the back spinning on an 8 3/4 or Dana 60. That would have to be the ultimit sleeper!!!
Oh and it has to ride stock, level hight.
