My 1997 Cadillac Seville is very comfortable. I like the quite ride with the adjustable seats and lumbar. It gets excellent gas milage for a luxury car. I averaged 24.5 MPG with my sales travel which was mostly highway. The Bose sound system, fingertip controls, and power to spare - to mention a few things - make this a very stable and dependable vehicle. I now have 175,000 miles on the car with only minor repairs.
I love the quiet, smooth ride with sporty takeoff power.
Allow the use of regular instead of premium gasoline (which is done on later models).
