Find one with Spotter →Typical sold price of a Cadillac STS ranges from $1,500 to $12,999, based on 1,368 sales tracked on Hypercars. 320 currently for sale.
The Cadillac STS arrived in 2005 as a replacement for the Seville, moving to the new rear-wheel-drive Sigma platform. It signaled Cadillac's intent to compete directly with German sport sedans, offering a choice between a 3.6L V6 and the 4.6L Northstar V8. The STS featured sharp, modern styling and advanced technology for its time, including available Magnetic Ride Control and all-wheel drive.
The collector highlight of the lineup is the STS-V, produced from 2006 to 2009. It packed a hand-built, supercharged 4.4L Northstar V8 good for 469 horsepower, paired with Brembo brakes and a strengthened chassis. With only about 2,500 built, the STS-V is a rare and potent American performance sedan that offers a unique alternative to an AMG or M-car from the same era.
Today's market sees standard STS models as affordable luxury cruisers, often trading for under $15,000. Their value proposition is high for a RWD V8 sedan. Pristine, low-mileage STS-V examples command the highest prices and represent the most collectible variant, while base models with high mileage make up the lower end of the market.
Buying Tips
- Check the 4.6L Northstar V8 carefully for any signs of overheating or coolant loss, as head gasket issues can be a concern.
- Verify all electronics work as intended, from the infotainment screen to the keyless entry system, as repairs can be costly and complex.
- On STS-V models, listen for excessive noise from the supercharger and inspect the expensive Brembo brake components for wear.
- Inspect the optional Magnetic Ride Control shocks for leaks, as replacements are expensive.
- Check for water ingress in the trunk and passenger footwells, often caused by clogged sunroof drains.
