Should I buy a used GMC Sierra 1500 now or wait for the next model?

Consider waiting if:

• Powertrain/efficiency: Base models get a 2.7-liter turbocharged four-cylinder engine dubbed TurboMax that produces 310 horsepower and 430 pound-feet of torque, and the Duramax turbodiesel 3.0-liter inline-six produces 305 hp and 495 lb-ft.

• Starting price: Pricing starts at $39,595 for a base Pro model with RWD and no frills.

If you're buying used today, the 2025 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for the next model year's inventory to build up.
