2009 Cadillac STS Overview

When it was new, reviewers praised the 2009 Cadillac STS for its performance, especially with the base V6 engine. In fact, many test drivers suggested avoiding the available V8 altogether since it offers only a tad more power and uses more fuel. Critics also liked the STS’ handling, saying that it offered a soft ride, but also could dive into the corners with ease.

The interior of the STS falls short, as reviewers thought the cabin is built well enough for a luxury car, but noted that there are too many cheap plastic surfaces inside. As a result, most test drivers agreed that Japanese and German rivals delivered a lot more interior refinement. Additionally, some critics noted the lack of rear-seat space, which makes the STS less practical than many sedans in the class. However, they appreciated the STS’ straightforward controls and comfortable front seats.

As a used car, the biggest weakness of the 2009 STS may be its poor safety score, which ranks at the bottom of the class. As a result, the 2009 STS may not be the ideal choice for shoppers who are looking for a safe used car.

Other Cars to Consider

If you want a luxury car with a cavernous interior, consider the 2009 Cadillac DTS. While the STS has a cramped back seat, the DTS is one of the most spacious cars in the class, and its smooth, comfortable ride makes it a stellar highway cruiser. 

The highly-ranked 2009 Acura RL comes standard with all-wheel drive and offers impressive cabin technology. Additionally, with exceptional safety scores, the RL makes an excellent choice among used luxury sedans.
