For 2011, the STS is no longer available with the Northstar V8 engine, leaving the 3.6-liter V6 as the sole power plant. All 2011 STS models are now covered by Cadillac's Premium Care Maintenance program.
Once hailed as the savior of the Cadillac brand, the STS luxury sedan now seems to be overshadowed by the brilliant CTS
Wagon, not to mention the impressive V-Series cars. Still, for those looking for luxury without hair-raising performance, the STS remains a crowd pleaser. Along with its slightly larger cousin, the DTS, the STS' mission is to continue satisfying the aging Cadillac faithful while still appealing to younger, first time buyers. Although it is available with all-wheel drive and a performance package suspension upgrade, the loss of the Northstar V8 engine this year will probably also cost the STS some potential buyers.
"Say what you want, this is a great car. I like it much better than the BMWs that I have owned in the past. Not a big fan of older caddies, but I love this STS. Onstar, XM, Nav, Bluetooth, Heated steering wheel, cooled seats, etc. Cant touch this quality for the money. Best GM sedan ever. I also like the new CTS! The caddy is back! Buy One and show your american pride. Why pay more for less. With the inflated euro, the german cars are way over priced for the vehicle. That is why I went to the STS. I am glad I did."
"I turned in a 2003 CTS for the 2005 STS and was amazed with the handling, power and breaking response. I really feel in control when driving this car. I have had a great many cars over the years. This is my 8th Cadillac. I usually get a new car ever three years and before retirement I would have three or four a year. I have problems when using other cars now. They do not move as fast or stop as well. I think Cadillac has done well with this."
