Used Car: 2010 Cadillac STS Review

Review Last Updated: 7/26/12

The 2010 Cadillac STS delivers balanced driving dynamics and power, but its poor safety scores and interior quality keep it from competing against the top large luxury cars.

The 2010 Cadillac STS is ranked:

If you’re seeking power and good handling, the STS is a solid alternative to European and Japanese luxury cars. Despite its large size, reviewers praised the STS’ driving dynamics, noting its powerful base V6 engine and smooth handling. They felt that the STS offered a soft ride, but could also dive into corners with ease.  

The STS also offers a V8 option, but reviewers said that it only adds slightly more power and uses more gas. Rear- or all-wheel drive is available with either engine. The STS gets up to 18/27 mpg city/highway, which is about average for the class. However, the STS has the lowest safety score in the class, and its reliability score, while not bad, isn’t competitive with many rivals’.

The STS’ interior quality falls well short of top competitors. When it was new, reviewers disliked the STS’ cabin because of its dull design, firm seats and lack of rear-seat space. While some reviewers thought the seats were comfortable, others thought they were too firm and needed more bolstering. However, test drivers liked the easy-to-use controls and cabin technology. Still, the STS’ 13.8 cubic feet of cargo space is less than what you’ll find in rival luxury cars.     

Leather upholstery, power front seats, dual-zone climate control, push-button start, satellite radio and OnStar come standard in the base Luxury Sport trim. Stepping up to the Luxury trim adds features like Bluetooth, heated and ventilated front seats, heated rear seats and a heated steering wheel, while the Premium model adds an upgraded stereo and navigation to the list of standard features.

Other Cars to Consider

The 2010 Infiniti M is a sportier alternative to the STS that’s worth a look. When it was new, reviewers raved about the M’s performance and power. If you choose the M, you’ll gain on performance, particularly tighter handling, and interior quality, though the STS gets slightly better fuel economy.

If you want a car that’s loaded with standard features, consider the 2010 Hyundai Genesis. While you won’t be able to get the Genesis with all-wheel drive, reviewers loved its comfortable ride and luxurious interior when it was new. Additionally, the Genesis offers significantly better safety and reliability ratings than the DTS, which may make it a smarter choice among used luxury cars.
