The Cadillac STS-V was the high-performance variant of the STS sedan, produced from 2006 to 2009. It was Cadillac's answer to German super sedans like the BMW M5 and Mercedes E55 AMG. The car's heart is its engine: a hand-assembled, supercharged 4.4L Northstar V8 known as the LC3, which produced 469 hp and 439 lb-ft of torque. This exclusive engine wasn't shared with any other GM product, making the STS-V a unique piece of Cadillac's performance history.
Collectors are drawn to the STS-V for its rarity and its special powertrain. With just over 2,500 units built, it's far less common than its CTS-V sibling or its German rivals. Its understated styling gives it a 'sleeper' quality that many enthusiasts appreciate, hiding its serious performance capabilities behind a conventional luxury sedan profile. It represents a brief, interesting chapter for Cadillac before the V-series fully adopted GM's small-block V8s.
The market for the STS-V is currently in a value-focused stage. With an average sale price around $15,000, these cars offer a tremendous amount of performance for the money. The wide price range, from under $2,000 to over $25,000, shows that condition, mileage, and maintenance history are the biggest factors in determining value. Top-dollar examples are low-mileage and perfectly maintained, while cheaper cars almost always need significant work.
Buying Tips
- Check the supercharged 4.4L Northstar V8 carefully for oil leaks, a common issue. A pre-purchase inspection should also include a coolant system pressure test.
- The Magnetic Ride Control shocks are a known failure point and are very expensive to replace. Look for visible leaks from the shock absorbers and check for any 'Service Suspension System' warnings on the dash.
- Test all interior electronics. The infotainment screen, keyless entry, power accessories, and climate control can all develop faults that are difficult and costly to diagnose.
- Inspect the Brembo brakes for pad and rotor life. These high-performance components are much more expensive to replace than the parts on a standard STS.
- The 6L80 automatic transmission is generally strong, but a test drive should confirm it shifts smoothly without hesitation. Deferred maintenance can lead to costly repairs.
Prices range from under $2,000 for project cars to over $25,500 for the best low-mileage examples.
