The 3rd generation GMC Sierra ran from 2007 to 2014 on the GMT900 platform, which it shared with the Chevrolet Silverado. GMC positioned the Sierra as a more premium offering, with distinct exterior styling, an upgraded interior, and more available features. Buyers could choose from a wide range of V6 and V8 engines, including the popular 5.3L and the powerful 6.2L V8.
Collectors are drawn to these trucks for their blend of modern performance and comfort without the complexity of later generations. The Denali trim is the most sought-after model, featuring a standard 6.2L V8, all-wheel drive, a unique chrome grille, and a luxury-appointed interior. Low-mileage, well-maintained examples of any trim, especially Crew Cabs with V8 power, are increasingly desirable.
The market for these trucks is broad, with an average sale price around $21,190. The wide price spectrum reflects the difference between high-mileage work trucks and preserved collector-grade examples. Top-tier Denali and SLT models are pulling away from the pack, commanding premium prices for clean, low-mileage condition.
Buying Tips
- Check for rust on the frame, rocker panels, cab corners, and above the rear wheel wells.
- The 5.3L V8 with Active Fuel Management (AFM) can suffer from collapsed lifters; listen for engine ticking and check for records of oil consumption.
- Test all interior electronics, especially on high-trim SLT and Denali models, as dashboards are also prone to cracking.
- On 4x4 models, inspect the transfer case and differentials for leaks and listen for whining noises that indicate bearing wear.
Prices range from under $2,000 for high-mileage work trucks to over $47,250 for pristine, low-mileage Denali models.
