2005 Cadillac DeVille DHS 4dr Sedan (4.6L 8cyl 4A)
I've got about 9,500 miles on my 2004 DHS. It's very powerful so it accelerates onto freeway with absolutely no problem. It's ride is a little firm - but maybe that is why the handling is so good. It's very secure in turns. I feel safe and comfortable in this car. All the bells and whistles work well. MY complaint is that you can't program the navigation system when the car is moving. So if you're on the freeway, you have to pull off if you want to impute a destination. My mileage - in city driving only (I've never taken it more than 70 miles from home) is about 17 to 18. If I use the freeways much, I'm usually in the 18 - 19 mpg range - which I consider excellent for a car this big.
Powerful engine; good looks. Radio controls.
Make ride a little softer. Allow programing of navigation unit when car is in motion.
