My 1993 Cadillac DeVille is a good car. I love it, the ride quality makes you feel like you are floating. It is the most comfortable car I've been in, but that goes for all DeVilles. It is solid (if you tap something it rarely even dents), she's a heavy car. The car still has plenty of power, only 200hp but a lot of torque, and a big V8. I have had to put $800 of work into it mechanically, but she's never died on me. I've had problems with the water pump, fuel pump, and a couple of things that a tune up could handle, but the even with those problems my DeVille has never let me down.
Very smooth ride and a good, powerfull engine.
When the car is in great condition there isn't much that could improve it.
