I’ve not looked it up, but I’d venture to guess that a ‘73 Fleetwood was one of the longest cars made. And, as you alluded to, absolutely bonkers length from wheel center to each bumper.

Our Hyundai has the opposite problem. Because the flat battery pack allows the wheels to be shoved to the corners, it looks smallish but has a longer wheelbase than Hyundai’s large Palisade SUV. Which makes it a pig to park.
