The 2010 Cadillac STS keeps in tune with the same classic look as previous models. It's a large luxurious car that makes a permanent impression when it is seen on the road. The large chrome grille with the Cadillac crest at the front gives the vehicle a look that says the car means business.
A large vehicle like the STS needs a powerful engine, and that comes in the form of a 3.6-liter V-6 that makes 302 horsepower in base trim. Alternatively, you can opt for a more expensive 4.6-liter Northstar V-8 that gets 320 horsepower. However, most reviewers enjoy the V-6 and don't see the point of paying extra for the larger engine. You'll pay around $9,000 for the V-8, which hardly seems worth it as there is not much more power added for your hard earned cash. You can expect to pay $46,845 for the base model, which is on the expensive side of the scale. Drivers tend to agree that the STS is a great handler, even on slippery surfaces. On touring and sports models there is the option of the Magnetic Ride Control suspension that gives the Cadillac an even smoother ride. The brakes are very responsive and stop the vehicle with virtually no hesitation.
In comparison to other sedans the interior quality of the Cadillac STS doesn't seem up to par. For a large car the seating in the back is on the small side, and the front seats could use some more padding, but overall they are comfortable. The setting procedure for the driver seat, mirrors, radio and climate controls are far more complicated than they need to be. There is the option of a blind spot indicator on the mirror, but it is easily blocked out with sunlight making it quicker and easier just to turn your head. The cargo space within the STS is not really acceptable for a vehicle of this type. The trunk space is 13.8 cubic feet and there are no real storage areas to speak of, the glove box is less than adequate.
Stability control, and front, front-side and side head-curtain airbags are standard on the STS. If you want additional safety features, such as, lane departure warning system and blind spot warning you will pay extra for them. Overall, the 2010 Cadillac STS looks like a great car from the outside, but is rather disappointing in certain areas on the inside. The power and handling are of superior quality, and the braking is responsive. You really have to be a Cadillac enthusiast to make it worth your while buying the STS.
