Grabbed this from another board. It has seemed to stir some debate on what kind of car it actually is. He lists it as a '75 El Camino but then in another part of the ad he says it's an "El Camaro"(???). Anyway you look at it,it's ugly.

1975 El Camino Camaro Vette Firebird Thing (http://auto-rv.com/default.asp?area=browsedetail&adname=CHI8510042)

looks to have been either a camaro or a firebird at one time, from looking at the roof line.

Id say it started as a 75 camero, but it has lots of 79 81 Z28 parts put on it when they customized it i don't like the look myself.
