How Does the 2009 Cadillac STS Compare to Other Sedan?
The 2009 Cadillac STS competed against the BMW 5 Series, Mercedes-Benz E-Class, and Lexus GS. In terms of performance, the STS with the V8 offered comparable power, but the BMW and Mercedes often provided a more refined driving experience. Feature-wise, the STS was competitive, although some rivals had more advanced technology options.
Reliability is where the STS falls slightly behind. The German rivals, while also prone to issues, often had a stronger reputation for overall dependability. The Lexus GS is generally considered the most reliable of the group.
Price-wise, the STS was often more affordable than the German competitors when new, and this holds true on the used market. However, this reflects the lower reliability perception.
Similar alternatives include the Lincoln MKZ (more comfort-focused) or Acura TL (more reliable but less luxurious). If reliability is a major concern, the Lexus GS is a better choice, even at a higher price point. If performance is paramount, the BMW 5 Series offers a more engaging driving experience.

Final Verdict: Is the 2009 Cadillac STS a Good Sedan?
The 2009 Cadillac STS is ideal for someone seeking a comfortable and stylish luxury sedan with a uniquely American flavor. It's a good value on the used market, but buyers should be aware of potential maintenance and repair costs. It's worth buying *if* you find a well-maintained example with a thorough service history. Opting for a lower mileage vehicle is crucial. The V6 engine might be a better choice for those prioritizing fuel economy and potentially lower repair costs. Avoid examples with obvious neglect or signs of deferred maintenance. A pre-purchase inspection by a qualified mechanic is highly recommended.
