Overview & Reviews

The 2008 Cadillac STS has been significantly updated. Beyond revised styling and a more luxuriously trimmed interior, several high-tech safety and performance options keep this all-American Cadillac competitive in the luxury sport sedan segment. The base-trim STS also features a more powerful and efficient 302-horsepower V6 coupled to a six-speed automatic transmission.

• Optional Bose stereo is one of the best in its class.
• Low price for a full-size luxury sport sedan, powerful new V6, nimble road feel for such a large car, sporty all-American looks, available all-wheel drive

• Sporty front seats might be too firm for some posteriors, interior plastics not quite up to the standards set by the top-ranked competition.

  Why German - 2008 Cadillac STS
  By OKCowboy - August 17 - 6:33 pm

  My first Caddy. I have owned many Lincolns, several Mercedes, a terrific Jag and some unmentionables over my almost 40 years of "business" driving. This car has great styling, exceptional sound system and many, many options. It is very responsive, quite and comfortable to drive. I drove all the "others" before I chose the caddy and price was not a concern. Im glad to be driving an American sport sedan. It looks good and drive great. Time will tell but so far its a winner.

  Stick with a luxury import - 2008 Cadillac STS
  By GM Never Again - August 4 - 10:36 am

  The car is fun to drive and is great when its not in the repair shop. I have had my STS in service 2 times in the last three months (BRAND NEW) for different problems. GM and Cadillac treat you like you bought a Chevy.You pay a high end price and get low end service. To sum it up, they suck and I will never buy a GM product again. High end imports are more reliable and give much better customer service.

  From 2 BMW to Cadillac... - 2008 Cadillac STS
  By Eric - July 29 - 11:48 pm

  After 2 BMW,I just bought my first caddy at 36 yrs old.I was just tired seeing BMW,G35,NEW C-class even the new CTS every corner. So I found a great STS. Its very comfy very luxurious and the space inside. The nav with the 15 speakers from Bose? Oh la la. Its the best oem sound system Ive ever heard, by the way I am a musician. Of course the mileage is so so I bought the v8. Funny that the hid light are not std for that car. Overall its a good value when reduce cause I wouldnt buy at full retail. I love everything about the car but its not BMW handling and driving experience. When you think about it who care were not formula 1 driver, right? Cadillac: the ultimate luxury experience? I guess

  The best value for your money! - 2008 Cadillac STS
  By Tony - July 20 - 10:33 pm

  I had S-class Mercedes and BMW 7 several times before. I changed my S500 and Im glad I did. Those fancy Germans are just not worth the money when it comes to compare.

  Driving the 2008 STS - 2008 Cadillac STS
  By Samlh - June 21 - 11:53 pm

  I bought the V8 style, because adaptive speed control was not available on the V6. I traded in my 2005 STS, and got a great deal on the purchase. To this point, I am very pleased with the car, although gas mileage has not been good. Hopefully, it will get batter as I put more miles on the car. Although my 2008 is still very new,I believe it is a big improvement over the 2005. The car looks and rides better. I believe I made a good decision in purchasing the 2008 STS.

  Try a Mercedes before buying this. - 2008 Cadillac STS
  By Neville - June 19 - 12:24 pm

  This is the worst car I have ever bought. I only have 56k miles on it, and have had many electrical issues, some of which have made the car unusable. The dealer service is expensive and incompetent. The car itself, when it works, is pleasant enough, but is totally unreliable. No wonder GM went broke making rubbish like this. Update: my local independent mechanic has repaired most of the electrical issues, and apart from minor issues which appear and then apparently fix themselves, the car is now relatively reliable.

  Best luxury sports sedan - 2008 Cadillac STS
  By Charlie Higgins - May 26 - 6:23 pm

  Since January my wife and I have driven this vehicle daily. At 250 miles we took off to Florida from Ohio and averaged 24 mpg at 68 mph. Many times I took it above 75. The six speed transmission feels almost continuously variable. We purchased the navigation option along with the luxury interior package and AWD. I agree 18" wheels would have been nice but the HD brakes are not compatible with this larger wheel. The car performance is smooth and controllable compared to the BMW 535 and the Mercedes E Series. We test drove the CTS and agree with other reviewer that there is no comparison . Quality is unassailable and with 5500 miles ytd we would purchase all over again.

  I Love My Boomer Sooner Red STS! - 2008 Cadillac STS
  By OKrahoma - May 18 - 8:57 pm

  This is my first Cadillac, & I love it! Everywhere I go, people tell me it is a beautiful car. I love the red of this car, & I love all of the chrome. We took it on a 2500 mile trip two months after buying it, & had a wonderful drive. We did have a problem when pulling over on the highway to change drivers. A rain- filled pot-hole crumpled the front end, not noticeable on the outside. A simple call to OnStar led us to the nearest dealer. The only option we did not get was the navigation system, & Im fine with that! My husband had wanted a Chrysler 300, & I sold him on this, & so far, hes happy with the car, & me! I love that smiling front end! (On the car!)

  STS not so good - 2008 Cadillac STS
  By David Lovitt - April 19 - 1:36 pm

  Car has been into shop twice with less than 400 miles on the odometer. Today it completely died after refusing to shift into any gear higher than second. Problems with stability control and antilock brake system at 200 miles. Also has some paint flaws that need to be addressed. Im sorry I tried so hard to buy this vehicle.

  Love this car! - 2008 Cadillac STS
  By Mark - April 18 - 1:05 pm

  I test drove a CTS first. It was just Ok. I then drove the STS and Wow. I was sold! Big difference. They want to sell you a CTS at sticker b/c they make more $ on them, but the STS is worth the extra money, it is much more car. Smooth, quiet, luxurious. This is quite simply a nicer car than the 5- series BMW and E-Class Mercedes without the price tag of the BMW or the poor quality of the Mercedes. I could not tell the difference in performance test driving the V-8 and V-6. The DI V6 feels like a V-8. This car simply babies you. Frustrating that you cant get AWD with all the toys in the V-6. I opted for all the toys on a RWD with the 18" chrome wheels package - Car looks awesome.
