What should I look for when buying a used 2023 GMC Sierra 1500?

Key things to evaluate:

• Trim level: The Pro keeps things simpler with the carryover infotainment layout, a 7-inch touchscreen, LED headlamps, remote keyless entry, cloth seats, daytime running lamps, and Bluetooth connectivity, but it misses some basic conveniences such as a tilt and telescoping steering column.
• Powertrain: You can find a 2.7-litre turbocharged four-cylinder, a 3.0-litre Duramax turbocharged inline-six diesel, a 5.3-litre V8, or a 6.2-litre V8. The diesel is the lively standout, while the turbo-four is the base engine and the V8s broaden the truck’s capability and character.
• Safety package: Standard equipment includes forward collision warning, automatic emergency braking, pedestrian detection, lane keep assist, lane departure warning, and GM’s Teen Driver system. Higher trims add blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, adaptive cruise control, a surround-view camera system, GM’s Safety Alert seat, and Super Cruise, while some of those features are not standard on lower trims.
• Infotainment: The base Pro uses a 7-inch touchscreen, while every other trim gets a 13.4-inch touchscreen with wireless Apple CarPlay and Android Auto. The updated system also includes Google-connected apps, and all but the base Pro get a 12.3-inch fully digital instrument panel.
• Fuel efficiency: The Duramax turbo diesel with rear-wheel drive returns 10.1 L/100 km in city driving, 8.1 L/100 km on the highway, and 9.2 L/100 km combined. With 4WD, it rises to 10.7 L/100 km city, 8.7 highway, and 9.8 combined. The gas turbo-four returns 12.7 L/100 km city, 11.2 highway, and 12.0 combined, while the 5.3-litre V8 returns 14.3/11.2/12.9 and the 6.2-litre V8 returns 16.7/14.0/15.5.

Which 2023 GMC Sierra 1500 trim should I buy?

The 2023 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 simplest choice if you want the most straightforward cabin and the lowest entry point, but you give up some convenience features that show up quickly on higher trims.
• SLE: This is the best-value trim for many shoppers because it adds a power-adjustable driver’s seat, heated front seats, a heated steering wheel, dual-zone automatic climate control, a fully digital instrument panel, a larger touchscreen, wireless Apple CarPlay and Android Auto, extra USB ports, and a Wi-Fi hotspot.
• Elevation: This trim keeps most of the SLE’s equipment and opens the door to additional options and packages, so it suits you if you want a more customised build without jumping straight to the pricier luxury trims.
• SLT: This is the step up for comfort-focused buyers, adding leather upholstery, an auto-dimming rearview mirror, a power-adjustable front passenger seat, and memory settings for the driver’s seat.
• AT4: This is the off-road-oriented choice, with standard 4WD, skid plates, a lifted suspension, a two-speed transfer case, and an upgraded air filter.
• AT4X: This is the more serious trail-focused trim, developed with AEV and fitted with steel bumpers, an integrated front winch, 18-inch wheels with 33-inch mud-terrain tyres, additional skid plates, upgraded Multimatic dampers, and electronically locking front and rear differentials.
• Denali: This is the luxury pick if you want premium styling, a Bose premium audio system, ventilated front seats, wireless device charging, and a camera view of the truck bed.
• Denali Ultimate: This is the top-end choice if you want nearly every feature available, including full-grain leather, massaging front seats, 22-inch wheels, a 12-speaker Bose premium sound system, and the integrated Kicker sound system in the Multi-Pro tailgate.

The Denali Ultimate comes with every available driver-assistance feature, including Super Cruise.

Is now a good time to buy a used 2023 GMC Sierra 1500?

• Deal availability: 36.7% of listings are priced as good or great deals.
• Inventory: There are 1,465 listings available.

What is the 2023 GMC Sierra 1500's resale value?

The current average of $49,041 CAD sits slightly below last year's $55,184 CAD.

That softer pricing can help you as a buyer today, but it also means a future seller may face a more competitive market if prices stay under pressure. The Sierra’s broad trim range and premium appeal should help support demand, especially for well-equipped versions. Still, the recent decline suggests resale values may be more sensitive to condition, mileage, and trim than they were a year ago.

Vehicles with solid owner satisfaction ratings, like this model year's 4.3/5, tend to retain buyer demand, which supports resale value over time.

Is the 2023 GMC Sierra 1500 safe?

The 2023 GMC Sierra 1500 earns a Top Safety Pick+ rating from IIHS and five-star ratings from NHTSA.

It earns a 9/10 safety score from our experts.

Standard safety equipment includes forward collision warning, automatic emergency braking, pedestrian detection, lane keep assist, lane departure warning, and GM’s Teen Driver system. Higher trims add blind-spot monitoring, rear cross-traffic alert, front and rear parking sensors, adaptive cruise control, a surround-view camera system, GM’s Safety Alert seat, and Super Cruise. The Denali Ultimate gets every one of those features, while lower trims do not.

Should I buy a 2023 GMC Sierra 1500 or consider a different year?

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 36.7% of listings are priced as good or great deals.
• Price trend: Prices have softened 11.13% compared with last year.
• Owners rate it 4.3/5 — a solid satisfaction signal.
• It adds the Denali Ultimate trim and keeps the Sierra’s upscale, tech-heavy full-size truck character.

Consider the 2022 if:

• At $45,870 CAD, the 2022 costs less than the current year's $49,041 CAD average.
• It brought a major makeover with bolder styling, a more lavish interior, and new high-end trims.

Consider the 2024 if:

• At $54,287 CAD, the 2024 costs more than the current year's $49,041 CAD average.
• It broadens the Sierra’s appeal with a well-rounded mix of work, off-road, and luxury capability.

The bottom line: If you want the strongest mix of features and current pricing, the 2023 is the main path to consider. If your priority is saving money, the 2022 is the better value play, while the 2024 makes sense if you want to spend more for a newer model-year alternative.
