I think this may very well have been the "Chrysler, it seats about 20" the B-52s sang about in "Love Shack":
1971 Chrysler Imperial Lebaron.
I've always had a soft spot for the luxobarges of the early 1970s through the mid-1980s. A good friend growing up had a 1982 Oldsmobile 98 as his first car, and I can't even begin to describe the unmitigated joy of double-dating in a car with a back seat roughly the size of a NYC studio apartment. I owned an '83 Caddy that sat 6 comfortably - each with their own ashtray, no less.
I like big cars and I cannot lie.
The Imperial was Chrysler's flagship line, and from 1955 through the car's end in the 1970s it was sold as a stand-alone model. It wasn't a Chrysler Imperial, it was the Imperial Crown or LeBaron (a marque that would be revised in the 1980s as something completely different from the luxobarge). The Imperial limousines are some of the most beautiful cars out there, IMHO.
They really don't make cars like this any more, and that's a shame.
That is all.
