They might be expensive new but if you keep your eyes open they can be found used at a good price. If you live in a bigger city it is not unusual to get one that’s been owned by more than one mortuary. Since the styles are kind of classic and they don’t get driven hard they do tend to stay in service for a longer time than a typical fleet vehicle.
I looked at one out of curiosity once and it had a pretty fair amount of miles on it but it was in good shape and was pretty cheap. But I swear something seemed to smell bad about the car. Could have been my imagination.
One thing to consider is you’re getting a 20’ long two-seater car. Great for child-less couples who eat a lot of groceries.
