back in the late 80's at the garage i worked at we had a chevy caprice classic areo coupe. the only one i've ever seen. it was green with a white vinal top.the owner bought a used 307 engine and we put it in. it set out in our driveway and ran for about 40 min. and used 3 quarts of oil. we pushed it into the don't no pile of cars and it sat there so long the roof rotted off of it. i mean the steel part under the vinal top.we ended up crushing the car. boy would i like to have it now. if anyone has seen or owned one of the areo chevys let us know.
