In the 1960s, a small team of gearheads from Texas revolutionized what everyone thought they knew about racing when they built the Chaparral 2J, a.k.a. the "sucker car." Why "sucker?" Because it literally sucked itself down to the ground, resulting in cornering that was truly frightening. It would've never existed if not for its predecessor, the Chaparral 1, hadn't shown them the benefits of on-going development. It's extremely rare to even see one, let alone find it for sale, so the fact that one of just three original Chaparral 1s is for sale at this week's RM Arizona auction is quite a good thing.
