I rode in a new Towncar back in '75...being pro GM and anti-anything else, I tried not to like it but to this day I'll say that Lincoln set the standard for ride. I'll have to add a caveat that I haven't ridden in many high end cars. Drove a V-12 4-door Jaguar sedan that gave the Towncar a run for its money but...nah, not really.
You could put a full size hot tub in the trunk of an old fleetwood.
