No rusted out top with a slick top. No interest in the car.
It seems that most Calais' I've seen don't have vinyl roofs. Perhaps because it was an "entry level" car they didn't want the option? Which I think is a good thing, they look nice without the vinyl.
Or maybe the ones with the vinyl roofs all rusted out and are in the junk yards.
