This giant parade float looks like a bargain at just $2500. Fresh paint would make it like new! https://greenbay.craigslist.org/cto/4601420009.html
Technically, if something happens to the back glass on this one, you won't have to worry about replacing it. You won't find another one, so you just throw the Olds away......
A friend had one in high school...in Jersey. It was a rust-bucket even then...23-years-ago. Had the Olds 403 in it...and it really needed a 455..ha! The window is still interesting.
GM used the curved rear window to much better advantage on the 1977-79 Caprice/Impala. Very sharp design. Much sought after these days as donks, unfortunately.
