2004 Cadillac DeVille DTS 4dr Sedan (4.6L 8cyl 4A)
I believe these sedans are very underrated. I love my DTS! The only things I would change: I would make an AWD version and the front cup holder (when flipped out) blocks the shifter from shifting into 1st gear. Last week I drove a 2006 DTS, loaded to the hilt. I can actually say I like the interior of my 2004 much better than the 2006. I do like the changes outside for 2006 though.
The interior door handles are very elegent. The wood trim is not too "Brown." The leather seats are soft and suple. The navigation system is great and the Bose stereo sounds great. The ergonomics in general seem to have been well thought out.
The front cup holder gets in the way of 1st gear. Add AWD. Give it express close for the rear windows and sunroof and larger front / rear rotors and calipers.
