Overview & Reviews
Though it evolved into an entirely different species, the luxury performance DNA of the Cadillac STS can be traced all the way back to the special range-topping Seville hardtop coupe of the 1950s. At that time one of the fastest, flashiest and most luxurious cars on the road, it evolved into various different forms over the course of several decades until emerging as the buttoned-down STS luxury sedan.
If you're in the market for a used luxury sedan with competitive amounts of power, roominess, comfort and value, a STS could be a good idea. However, it was largely eclipsed in terms of performance and luxury by competing Japanese and European sedans in its later years. Even its smaller CTS sibling offered better performance and handling, a much nicer interior and class-competitive interior space.
Most Recent Cadillac STS
The Cadillac STS was a rear-wheel-drive luxury sedan that was produced from 2005 through 2011. A midcycle refresh took place for '08, bringing revised styling, a more luxuriously trimmed interior and a new base engine. We suggest focusing your search on cars from these later model years.
Originally, the STS came standard with a 255-horsepower 3.6-liter V6 and a five-speed automatic. This was replaced by a 302-hp V6 and six-speed auto for 2008. With the exception of the STS's final model year in 2011, buyers could opt for a 320-hp 4.6-liter V8 coupled to a six-speed auto. Originally, each engine represented a different trim level, as the V8 came standard with the V6's optional heated front and rear seats, memory functions, heated steering wheel and automatic wipers. Key options to look for included a magnetically controlled adaptive suspension, adaptive cruise control, a navigation system and ventilated front seats.
For 2010 and 2011, however, trim levels were introduced. The V6 came in Luxury Sport, Luxury and Premium trims, while the V8 was available in Luxury and Performance. The actual equipment that was available didn't really change. Many of the previous options were simply redistributed into the upper trims, though it should be noted that all but the V6 Luxury trims got upgraded braking, steering and cooling systems.
In reviews and road tests, our editors found the strengths of the Cadillac STS to include surprising agility, respectable performance and a high-quality audio system. Downsides include a somewhat old-fashioned feel compared to its rivals, a small trunk and hit-or-miss interior quality. Overall, it's hard to fully endorse this full-size luxury sedan when Cadillac's own smaller CTS from the time offered a more involving drive while only giving up a bit of interior space to its big brother.
Previous Cadillac STS Models
Used shoppers may come across an older STS. Technically a trim level (there was also an SLS), this is actually the front-wheel-drive, fifth-generation Seville produced from 1998-2003. The STS was the "performance-oriented version" of that car and featured a more powerful V8 engine along with more luxury features. The 1992-'97 Seville also featured a similar STS edition.

Love the new STS - 2008 Cadillac STS
By Dominic - October 9 - 1:09 pmI just traded in my 2003 v-8 FWD SLS for a new 2008 v-6 STS RWD. Having driven the 03 for 4 years and the 08 for only a few weeks short weeks, I can say that the 08 is by far a better car. That is not to say anything bad about the 03, just that Cadillac got it right with this one. RWD, IMHO, is a much better way to design and build this class of car. I got the car pretty much loaded up. Sticker was ~$54K. The larger 18" wheels included in the 1SC Luxury Performance package, along with the HD brakes really make this a driving machine.

My First Cadillac - 2008 Cadillac STS
By TexasPhotographer - October 3 - 10:27 pmI like this car. However, the manual reads like it was written in a language other than English. Instead of providing information, the manual refers you to two other pages to get the information. The navigation system is nice, but difficult to learn and again the manual is little to no help. The seats are comfortable and I like the sporty ride. The glove compartment is way too small. I do not like the fact that when opening the trunk, it does not open fully. As a photographer I have arms full of equipment. I would have liked the trunk to open so I could put the equipment in the trunk instead of on the ground so I can manually open the trunk. Not a convenient feature.

Cadillac STS Awd - 2006 Cadillac STS
By Cadillac STS - September 15 - 12:39 pmIve had my STS 14 months now.I dont know what problems other people are having, but my STS has not seen the dealer since I bought it. The only thing I have done is changed oil at 9400 miles and rotate the tires at the same time. I average 20 mpg , not bad could be better. The exterior design is beautiful, although standard wheels should be 18s. The interior is beautiful with exception of cheap hard plastics on the center stack. Seats are to firm. Overall I love the car, well that is until I saw the 08 CTS. I kind of feel like I am driving an old mans car next to the new CTS.

2nd STS for me, and I love my 07!! - 2007 Cadillac STS
By tj65 - September 7 - 9:37 pmThis is my 2nd STS. I expected a lot of my new 07 STS and have been very pleased so far! Cars I considered before buying my STS - all very nice but either too small or offered less value: 1. Acura TL and RL 2. Lexus GS and IS 3. Infinity M35 4. Subaru Tribeca 5. Audi A6 6. Mercedes E Class 7. BMW 5 Series 8. Volvo S70 The 07 STS handles like a sports car with luxury feel exacly what I was looking for! Its quick for a V6 - I test drove the V6 and V8, and there was not a huge difference to justify the incremental cost. I looked at a bunch of cars, and the STS, in my opinion, gave me by far the best bang for the buck (see favorite features below) Very pleased so far!

08 STS is hot - 2008 Cadillac STS
By Cosmo - August 11 - 9:28 am302-horsepower engine with direct injection V6. A bolder look on the outside and inside will attract younger buyers. I am 41. I wanted a 4 wheel drive car that can accommodate 3 car seats in the back. I looked at the BMW 535xi, Lexus GS350 AWD Infiniti M35 (currently drive Infiniti M45) at Audi A6. For the money the 2008 I stress the 2008 STS was the best value. The increased performance and the side air extractors, incorporated into the front fenders of STS. New chrome-plated door handles and lower rocker moldings are added for more presence and refinement.

Cadillac Man! - 2006 Cadillac STS
By Mark Anthony - July 27 - 1:45 pmThis is my 5th new Cadillac and so far the best. People are in awe when I tell them the features. Windows down by voice, push button start, keyless access, just walk up to the car and the car door opens automatically. 15 speaker Bose stereo and navigation screen, it even plays DVDs and MP3s! The automatic transmission shifts without the clutch. I just love this car. I clean it everyday!
