Actually I was 12 yrs old when this car was made. I remember seeing the Impalas my whole life though, and couldn't resist.
I test drove a 2dr a couple years back, the interior wasn't as good as this one, the guy wanted almost 10K for it, and he didn't have the title (but said he could get it). So I walked.
Well, at least it'll keep me outa trouble working on it!
The reason I said that is because there were a lot of chevy's and I think pontiacs too that put the gas cap there in the 60's and early 70's. Makes me wonder how many housewives in those days ran out of gas because they couldn't find the gascap, and didn't have a way to call their hubbys. LOL.
