My most reliable, by far, is a 1956 Studebaker President. Followed by a ‘99 Lincoln Town car, a 98 Mark 8, and a 92 Suburban. (Technically, the Suburban is completely rebuilt.)
My Lincoln dealer says they have a waiting list of people who want a Town Car if they come in on trade. I love those old land yachts!
