Should I buy a used GMC Sierra 2500HD now or wait for the next model?

It produces power specs of 470 horsepower and, wait for it, a staggering 975 lb-ft of torque.
• Tech: This includes a 15-inch multi-colour head-up display, wireless Apple CarPlay and Android Auto connectivity, wireless device charging pad, Google built-in, 12-speaker Bose surround-sound audio system, and split-screen navigation.
• Safety: The GMC Sierra HD comes standard with both of these features, along with others such as pedestrian detection and lane departure warning.

• Starting price: The 2024 GMC Sierra 2500 Denali Ultimate heavy-duty pickup truck has a base price of $125,630.

If you're buying used today, the 2024 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.
