I have been driving Cadillacs for the past 16 years. I have had DeVille's and SLS's. Always I could rely on Cadillac to provide superior ride and service. My 2006 STS V6 was a huge disappointment. We have 8,000 miles on the car and have felt every crack in the road from here to Florida and back. We cancelled a Christmas driving trip and chose to fly. The ride is intolerable. Never before have we had to test drive the car before ordering. We find that the only smooth ride offered by Cadillac is the DTS. We like the sporty styling but its a tin-lizzy dressed in sports attire. Second, the glove box is not sufficient to even house the car's instruction manual. What a useless piece of space.
Styling and performance.
Make the car ride like the Caddy's of old. The STS is a disgrace.
