This car is a dream to drive. Even though I have only had it for 2 months, I have taken it on several trips out of town. The city mileage could use some help. The only complaint I have is with the poor design of the seatbelts. I am a short person (5'5") and I find that the seatbelt hits me across the neck. It is not adjustable, as it comes out of the top side of the seats. They work fine for my husband, but he is 6'4". In other cars we have owned, you had a slide feature to raise or lower the seatbelt. I have raised my seat, but that is not enough to help. This could be a safety issue if you are in an accident. Other than that I love my DeVille.
Air conditioned front seats, satellite radio, sunroof, and settings for each driver.
Needs improvement on the seatbelts so they won't run across the neck. I raise my seat, but that still isn't enough.
