I’ve seen a lot of Lincoln Town Cars around where I live. In fact, although it might just be memory bias, I’ve seen more Town Cars than the related Crown Victoria sedans. Or it might not be, since the lower-budget Crown Vics probably had less effort put into maintaining and preserving them than the luxurious Town Cars.
I’ve never actually ridden in one and probably never will, although I’ve heard they’re the ultimate in squishy American comfort.
