Hoopty?

[Douglas G. Wilson]

The only dictionary entry I find is in the Cassell slang dictionary:

"hooptie/hoopty/hoopdee n. 1 [1960s-80s] (US orig. Calif.) a car, esp. the
latest model. 2 [1990s] (US Black) a worn-out, falling-to-pieces automobile
..."

Presumably the same car which fitted sense 1 in 1970 might fit sense 2 in 1995.

Original etymology? One can't help thinking of "whoop-de-do". (And "Coupe
de Ville"?)
