1995 Cadillac DeVille. So random, right? When I first moved to Vegas, we bought one for CHEAP, from a repossession sale. That car was amazing. So easy to handle, and it felt like you were in a tank, that was floating across the ground. I always felt so safe driving that car. But it was in bad condition to begin with and eventually we had it junked.
Or, if I were just buying a car for my showroom, I'd get a 1982 Jaguar XJS. My dad had one in red, and he used to joke that he loved me, then the car, and then everyone else. It has a lot of sentiment attached.
