Used 2024 GMC Sierra 1500 for Sale nearPortland, ME

How much does the 2024 GMC Sierra 1500 cost?

Prices have softened 10.64% compared to this time last year, making it a favorable time to shop this model year.

There are 9,639 listings available, which suggests you have a healthy amount of inventory to compare.

Is the 2024 GMC Sierra 1500 a good car?

Yes — 4.64/5 owners rate it, which is a strong sign that you’re looking at a truck that satisfies a lot of buyers. The expert rating is 7.17/10.

The model scores 8/10 across Performance, Form and function, and Technology.

Owners repeatedly 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 positives, especially if you want a truck that feels more polished than purely work-focused.

The trade-offs are that not all advanced safety features are standard, and the truck’s value for money is described as poor.

That fits the Sierra 1500’s role well: you’re getting a truck that can serve as a basic work vehicle, an off-roader, or a luxurious long-distance cruiser, depending on how you configure it. Good and great deals account for 32.1% of listings, so there’s still some room to shop carefully.

Is the 2024 GMC Sierra 1500 reliable?

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

Owner feedback points to a truck that feels dependable in daily use, with many shoppers highlighting its strong engine performance, comfortable cabin, and generally satisfying ownership experience. The same feedback also suggests some concern around infotainment reliability and emissions-related issues, so you should pay attention to how the truck’s tech and powertrain have behaved over time.

The diesel powertrain is described as smooth, linear, and well suited to towing, while the 10-speed automatic is praised for smooth, quick shifts. That combination supports the impression of a truck built to handle long-term use without feeling strained.

If you’re buying used, the main ownership risk is making sure the truck’s electronics and powertrain history are clean before you commit.

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 history report on any truck you’re seriously considering, even with a strong accident-free share in the market. Prioritize a pre-purchase inspection if the truck has higher mileage, towing use, or any signs of uneven wear. Focus especially on cabin condition, infotainment behavior, and whether the truck’s equipment matches the trim level you expect.

Key things to evaluate:

• Trim level: The base Pro is aimed at commercial fleets and is much more basic than the higher trims, while Denali and Denali Ultimate lean into luxury and AT4/AT4X focus on off-road capability. The Pro’s black grille and painted 17-inch wheels make its feature gap obvious, so you should compare equipment carefully if you want more comfort or convenience.
• Powertrain: You can choose a 2.7-liter turbocharged four-cylinder, 5.3-liter V8, 6.2-liter V8, or Duramax 3.0-liter turbodiesel. The diesel stands out for its torque and fuel economy, while the V8s add more power and the TurboMax is the entry-level option.
• Safety package: Standard equipment 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, so check carefully for gaps on the truck you’re considering.
• Infotainment: Base Pro models use a 7-inch touchscreen with Bluetooth and wired Apple CarPlay and Android Auto. SLE and higher trims get a 12.3-inch digital instrument cluster, a 13.4-inch touchscreen, wireless Apple CarPlay and Android Auto, and Google Built-In.
• Fuel efficiency: The Duramax diesel is rated at 25 mpg combined with RWD and 24 mpg combined with 4WD. The TurboMax 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 lowest entry price and don’t need much luxury equipment. It’s the trim most clearly aimed at fleets, so it’s best if value and utility matter more than comfort features.
• SLE: This is the first trim that moves you into the more modern tech experience, including the larger touchscreen and digital instrument cluster. It’s the best-value choice if you want a more complete daily-driver setup without jumping deep into luxury pricing.
• Elevation: This trim adds a more upscale look while staying below the premium end of the lineup. It suits you if you want style and convenience without paying for the top luxury trims.
• SLT: This is the step-up choice for shoppers who want more comfort and a richer feature mix before reaching the luxury-focused models. It’s a sensible middle ground if you want a more polished truck without going all the way to Denali.
• AT4: This is the off-road-oriented pick, with a 2-inch lift, Rancho monotube shocks, a locking rear differential, and skid plates. Choose it if you want trail capability and a tougher setup.
• AT4X: This is the more serious off-road version, adding a front locker and more sophisticated dampers. It’s the right choice if you want the most capable off-road hardware in the standard lineup.
• Denali: This is the luxury trim that brings the Sierra’s upscale personality to the forefront, including the signature chrome grille and available 22-inch wheels. It’s the right fit if you want a premium-feeling truck for everyday use.
• Denali Ultimate: This is the top luxury choice, and it’s the one to buy if you want the most comfort and the richest feature content. It’s the clear pick for shoppers who want the Sierra to feel as close to a luxury vehicle as possible.

Denali and Denali Ultimate can also be equipped with Super Cruise, so if hands-free driving matters to you, those trims deserve a close look.

Is now a good time to buy a used 2024 GMC Sierra 1500?

The market looks moderately favorable if you’re a selective buyer.

• Deal availability: 32.1% of listings are priced as good or great deals.
• Inventory: There are 9,639 listings available.
• Price trend: Prices have softened 10.64% compared with last year.
• Clean inventory: 93.3% of listings are accident-free.

If you find a listing below $48,552, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $48,552 sits slightly below last year's $54,335.

That decline suggests the market has cooled, which can help you as a buyer but may pressure future resale if you plan to sell soon. If prices stay soft, you may not recover as much of your purchase price as you would in a stronger market.

On the other hand, the Sierra’s broad appeal, strong feature set, and premium positioning can help it stay desirable with used-truck shoppers. Trucks with the right equipment and clean history usually hold up better than stripped or heavily worn examples.

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 Crew Cab earns Good ratings in the driver-side small overlap front test, the original moderate overlap front test, and the original side crash test from IIHS, but it also earns an Acceptable score in the updated side crash test and a Marginal score in the passenger-side small overlap front test. Crew cab models receive five-star ratings for side-crash protection, four-star ratings in rollover and frontal crash testing, and a five-star overall safety rating from NHTSA.

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

Standard safety equipment 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.

That uneven crash-test performance is the main caution here, so you should pay close attention to the exact cab configuration and safety equipment on any used example you’re considering.

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:

• 32.1% 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 10.64% compared with last year.
• Owners rate it 4.64/5 — a strong satisfaction signal.
• The 2024 model keeps the Sierra’s broad mix of work-truck utility, off-road capability, and luxury appeal while adding a fuel-efficient diesel option and easy-to-use tech.

Consider the 2023 if:

• At $45,333, the 2023 costs less than the current year's $48,552 average.
• It emphasizes upscale luxury and cabin space, with a strong focus on premium-truck appeal.

The bottom line: If you want the newer truck with a softer market and strong owner satisfaction, the 2024 is the better all-around pick. If your priority is saving money up front, the 2023 is the smarter value play, especially if you find one with the right equipment and condition.
