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

Key things to evaluate:

• Trim level: The Pro is the simplest version, with a 7-inch touchscreen, Apple CarPlay, Android Auto, LED headlamps, remote keyless entry, cloth seats, daytime running lamps, and Bluetooth connectivity, but it misses some basics such as a tilt and telescoping steering column. The SLE adds a power-adjustable driver’s seat, heated front seats, a heated steering wheel, dual-zone automatic climate control, a wall-style power outlet, a fully digital instrument panel, a larger touchscreen, wireless Apple CarPlay and Android Auto, extra USB ports, and a Wi-Fi hotspot. The SLT adds leather upholstery, an auto-dimming rearview mirror, a power-adjustable front passenger seat, and memory settings for the driver’s seat. The AT4 is the off-road-oriented choice with 4WD, skid plates, a lifted suspension, a two-speed transfer case, and an upgraded air filter. The AT4X adds steel bumpers, an integrated front winch, 18-inch wheels with 33-inch mud-terrain tires, additional skid plates, upgraded dampers, and locking front and rear differentials. The Denali adds unique styling, a Bose premium audio system, ventilated front seats, wireless device charging, and a camera view of the truck bed. The Denali Ultimate adds nearly every feature optional on other trims, including full-grain leather, massaging front seats, 22-inch wheels, and a 12-speaker Bose premium sound system.
• Powertrain: You get a 2.7-litre turbocharged four-cylinder with 310 horsepower and 430 pound-feet of torque, a 3.0-litre Duramax turbocharged inline-six diesel with 305 hp and 495 lb-ft, a 5.3-litre V8 with 355 hp and 383 lb-ft, or a 6.2-litre V8 with 420 hp and 460 lb-ft. The diesel is described as lively and well matched to the 10-speed automatic, while the turbo-four uses an eight-speed automatic.
• 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 can 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 GM’s Super Cruise driver assist system. The Denali Ultimate gets every one of those features.
• Infotainment: The base Pro uses a 7-inch touchscreen with Apple CarPlay and Android Auto. Every other trim gets a 13.4-inch touchscreen with wireless Apple CarPlay and Android Auto, Google-connected apps, a volume dial, and a home button. All trims but the base Pro also get a 12.3-inch fully digital instrument panel.
• Fuel efficiency: The Duramax turbo diesel with RWD returns 10.1 L/100 km in city driving, 8.1 on the highway, and 9.2 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. 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 value-focused starting point if you want the Sierra’s core capability and the simpler carryover infotainment layout, but you’ll 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 heated seats, a heated steering wheel, a larger touchscreen, wireless smartphone integration, and a digital instrument panel.
• Elevation: Choose this if you want much of the SLE’s equipment with a more style-forward presentation and access to additional options and packages.
• SLT: This is the right step up if you want a more premium cabin, thanks to leather upholstery, memory settings, and a power-adjustable front passenger seat.
• AT4: Pick this if you want the off-road-oriented setup, including 4WD, skid plates, a lifted suspension, and a two-speed transfer case.
• AT4X: This is the more serious trail-focused choice, with locking differentials, upgraded dampers, mud-terrain tyres, and an integrated front winch.
• Denali: This trim is for you if you want luxury touches such as ventilated front seats, a Bose audio system, wireless charging, and a bed-view camera.
• Denali Ultimate: This is the top-end pick if you want the most complete feature set, including massaging front seats, full-grain leather, and the most upscale cabin presentation.

The safety package starts with strong standard equipment, but the most advanced driver-assistance features are reserved for higher trims, especially the Denali Ultimate.

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

This is a moderate market for selective buyers, so it rewards patience and comparison shopping.

• Deal availability: 36.5% of listings are priced as good or great deals.
• Inventory: There are 1,450 listings available.
• Price trend: Prices have softened 11.55% compared with last year.

If you find a listing below $48,619 CAD, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $48,619 CAD sits slightly below last year's $54,967 CAD.

That softer pricing can help you buy in at a more favourable point, but it also means future sellers may face a less aggressive market than they did a year ago. If prices continue to normalise, resale values could stay under pressure unless demand strengthens or supply tightens.

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 designation 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 GM’s Super Cruise driver assist system.

The main caveat is that some of the most advanced driver-assistance features are not standard, so you may need to move up the trim ladder to get the full suite.

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:

• 36.5% of listings are priced as good or great deals.
• Price trend: Prices have softened 11.55% compared with last year.
• Owners rate it 4.3/5 — a solid satisfaction signal.
• It adds the Denali Ultimate trim and keeps the lineup focused on luxury, tech, and versatility.

Consider the 2022 if:

• At $45,323 CAD, the 2022 costs less than the current year's $48,619 CAD average.
• It brought a major makeover with bolder styling, a more lavish cabin, and new high-end trims.

Consider the 2024 if:

• At $53,735 CAD, the 2024 costs more than the current year's $48,619 CAD average.
• It broadens appeal with easy-to-use technology and strong versatility across work, off-road, and luxury roles.

The bottom line: If you want the best mix of current pricing and strong feature content, the 2023 is the sensible default. If you’re more price-sensitive, the 2022 is the value play, while the 2024 makes sense if you want to spend more for a newer model-year alternative.
