I was around back then and my second new car was a 71 chally, blue with a white top and interior AND a powered sunroof.
When I traded it in back in 1977, to me it was a 6 year old piece of crapola.
What an idiot I am.
But I remember it, the quads, as strictly a new year model freshening up, as some thing had to change to distinguish it from the 70 model. Detroit always made some year to year changes or why buy a new model when it's the same as a previous years model.
HP2 posted a reference to being cartoonish.
Back then I remember thinking that very thing about the daytona's towel rack spoiler.
