Used 2024 GMC Sierra 1500 for Sale nearDenver, CO

How much does the 2024 GMC Sierra 1500 cost?

Prices have softened 10.88% compared to this time last year, making it a favorable time to shop this model year.

There are 9,636 listings available, which suggests solid inventory availability. If you find a listing below $48,667.28, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2024 GMC Sierra 1500 a good car?

Yes — the 2024 GMC Sierra 1500 earns a 4.64/5 user rating, and the expert rating is 7.17/10. The model scores 8/10 across Performance, Form and function, and Technology.

Owners consistently praise the powerful engine choices, the comfortable and spacious interior, and the well-equipped feature set. The design and upscale feel also come up often as strengths, especially if you want a truck that feels more premium than purely utilitarian.

The trade-offs are familiar: some owners mention infotainment reliability concerns, and the truck’s value for money is described as weak. That fits the Sierra’s role as a versatile pickup that can work as a basic truck, an off-roader, or a long-distance cruiser, but may ask you to pay more for the experience than some rivals. Even so, 33.6% of listings are good or great deals, which gives you some room to shop selectively.

Is the 2024 GMC Sierra 1500 reliable?

Owners rate it 4.64/5, a strong signal of long-term satisfaction.

The owner feedback points to a truck that feels powerful, comfortable, and generally well liked over time. The summary also highlights concerns around infotainment reliability and emissions controls, so the ownership story is not spotless.

The expert evaluation reinforces that the Sierra’s powertrains are smooth and well mannered, with the diesel especially standing out for refinement and everyday drivability. GMC also backs the truck with a three-year, 36,000-mile bumper-to-bumper warranty and a five-year, 100,000-mile powertrain warranty, which helps reduce early ownership risk.

For used buyers, the main long-term risk is that higher-tech features and complex powertrains can be more expensive to live with if prior maintenance was neglected.

What should I look for when buying a used 2024 GMC Sierra 1500?

Accident-free inventory is excellent at 93.3% — clean inventory, standard diligence applies.

You should still run a vehicle history report and prioritize a pre-purchase inspection, especially if you’re considering a higher-trim truck with more technology and driver-assistance equipment. Focus on overall condition, feature operation, and signs of heavy use if the truck was worked hard or used for towing.

Key things to evaluate:

• Trim level: The Pro is aimed at commercial fleets, while the higher trims lean into luxury and off-road capability. Base models are also more basic visually and in equipment, so you should expect feature gaps there.
• Powertrain: You can choose from a turbocharged four-cylinder, two V8s, or a turbodiesel inline-six. The diesel stands out for torque and efficiency, while the V8s add more power.
• Safety package: Automatic emergency braking with pedestrian detection, forward collision warning, lane-keep assist, lane-departure warning, and a rear-seat reminder are standard. Adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, park assist, and the Safety Alert driver’s seat are optional, and Super Cruise is available on Denali and Denali Ultimate.
• Infotainment: Base Pro models get a 7-inch touchscreen with Bluetooth and wired Apple CarPlay and Android Auto. SLE and higher models upgrade to a 13.4-inch touchscreen, a 12.3-inch digital instrument cluster, wireless Apple CarPlay and Android Auto, and Google Built-In.
• Fuel efficiency: The Duramax diesel is EPA-rated at 25 mpg combined with RWD and 24 mpg combined with 4WD. The TurboMax four-cylinder can reach 20 mpg combined in some configurations, while the V8s return a few mpg less.

Which 2024 GMC Sierra 1500 trim should I buy?

The 2024 GMC Sierra 1500 is offered in 8 trim levels: Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate.

Here's the short version:

• Pro: This is the work-focused starting point, and it makes sense if you want the Sierra’s core capability at the lowest entry price. It is the least expensive path into the lineup, but it is also the most basic in equipment and tech.
• SLE: This is the best-value trim for many shoppers because it adds the larger 13.4-inch touchscreen, wireless smartphone connectivity, and the 12.3-inch digital instrument cluster. If you want the Sierra to feel modern without jumping deep into luxury pricing, this is the trim to target.
• Elevation: Choose this if you want a more distinctive look and a step up in presentation without going all the way to the luxury end. It builds on the SLE’s tech foundation and gives you a more upscale feel.
• SLT: This is the better pick if you want a more premium everyday truck with broader comfort and convenience appeal. It sits in the middle of the lineup and is a sensible bridge between mainstream and luxury trims.
• AT4: This is the right choice if you want the off-road setup, including the lift kit, Rancho shocks, locking rear differential, and skid plates. It also gets the diesel as standard for 2024, which strengthens its capability and efficiency mix.
• AT4X: Pick this if you want the most serious off-road hardware in the standard lineup, including the front locker and more advanced dampers. It is the trim for buyers who want the Sierra’s rugged side taken further.
• Denali: This is the luxury-focused trim for buyers who want the signature chrome look and a more upscale cabin experience. It also opens the door to advanced comfort and driver-assistance features.
• Denali Ultimate: This is the top luxury choice if you want the most richly equipped Sierra 1500. It is the trim that best matches the truck’s upscale ambitions and is the one to buy if comfort and premium features matter most.

Safety-package note: Super Cruise is available on Denali and Denali Ultimate, while several other driver-assistance features remain optional rather than standard.

• Inventory: There are 9,636 listings available.
• Price trend: Prices have softened 10.88% compared with last year.

What is the 2024 GMC Sierra 1500's resale value?

The current average of $48,655 sits slightly below last year's $54,594.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable point in the cycle. If you plan to sell later, the current softness means your near-term depreciation risk is still real, especially if you buy at the upper end of the range.

The upside is that the Sierra’s broad appeal should help support demand, particularly for well-equipped trims and cleaner examples. Trucks with strong owner satisfaction tend to hold buyer interest better, and that can help resale value over time.

Vehicles with strong owner satisfaction ratings, like this model year's 4.64/5, tend to retain buyer demand, which supports resale value over time.

Is the 2024 GMC Sierra 1500 safe?

The 2024 Sierra 1500 received a Good score in the IIHS driver-side small overlap front crash test, but a Marginal score in the passenger-side version. It also earned Good scores in the IIHS original moderate overlap front and side tests, plus an Acceptable score in the updated side crash test. In NHTSA testing, crew cab models received five-star overall safety ratings and five-star side-crash ratings, with four-star ratings in rollover and frontal crash testing.

It earns a 6/10 safety score from our experts.

The standard safety suite includes automatic emergency braking with pedestrian detection, forward collision warning, lane-keep assist, lane-departure warning, and a rear-seat reminder. Adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, park assist, and the Safety Alert driver’s seat are optional. Super Cruise is available on Denali and Denali Ultimate, and it adds hands-free driving capability for long trips.

The main caveat is that crash performance is uneven, especially in the passenger-side small overlap test and the updated side test. That means you should pay close attention to trim level and equipment if safety tech matters to you.

Should I buy a 2024 GMC Sierra 1500 or consider a different year?

If you're weighing the 2024 against nearby model years, here's how to think about it:

Choose the 2024 if:

• 33.6% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 93.3% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 10.88% compared with last year.
• Owners rate it 4.64/5 — a strong satisfaction signal.
• The 2024 keeps the Sierra’s broad trim range, strong powertrain choices, and available Super Cruise.

Consider the 2023 if:

• At $45,476, the 2023 costs less than the current year's $48,655 average.
• It adds the Denali Ultimate trim and pushes pickup luxury further.

The bottom line: If you want the newer model-year pricing trend, strong inventory, and the latest version of the Sierra’s feature set, the 2024 is the better default choice. If your priority is saving money upfront and you’re comfortable with an older model year, the 2023 is the more price-sensitive path.
