What is a good last car.?

All kinds of people ask the same question over and over, "what is a good first car?". So, I am getting up in years and thought I would ask "what is a good last car?" The car you would buy if you were getting old and this might be the last one? Would you get the biggest SUV you could so you could safely run into things? Would you get the Shelby you never had in your youth? Would you look for one with a warranty as long as your life expectancy is? What about something that would appeal to your grandchildren after you are gone? Would you look for one that had automatic everything or a simple one that you could operate the radio and heater without reading the owner's manual?
