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

Key things to evaluate:

• Trim level: The base 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. It also misses some basic features, including 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 most efficient setup, and it is described as lively and well served by the 10-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 add more advanced features, and Denali Ultimate gets the full suite, including Super Cruise.
• Infotainment: Every trim but the base Pro gets a 13.4-inch touchscreen with wireless Apple CarPlay and Android Auto. The updated system also uses Google-connected apps, while the Pro keeps the simpler 7-inch setup.
• Fuel efficiency: The Duramax turbo diesel with RWD returns 10.1 L/100 km in the city, 8.1 on the highway, and 9.2 combined. With 4WD, it rises to 10.7 city, 8.7 highway, and 9.8 combined. The gas turbo-four returns 12.7 city, 11.2 highway, and 12.0 combined, while the 5.3-litre V8 returns 14.3/11.2/12.9. The 6.2-litre V8 with mud terrain tires is the least efficient at 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 carryover infotainment system with a 7-inch touchscreen, Apple CarPlay, and Android Auto. It is the least expensive path into the Sierra 1500, but it also leaves out some convenience features.
• 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 larger touchscreen, wireless Apple CarPlay and Android Auto, extra USB ports, and a Wi-Fi hotspot.
• Elevation: This trim keeps most of the SLE equipment and opens the door to more options and packages, so it makes sense if you want a more personalised build.
• SLT: This is the comfort-focused step up, 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 model, developed with AEV and fitted with steel bumpers, an integrated front winch, 33-inch mud-terrain tyres, additional skid plates, upgraded Multimatic dampers, and electronically locking front and rear differentials.
• Denali: This is the luxury trim that adds unique 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 luxury pick, with nearly every feature optional on other trims, plus 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 safety package expands as you move up the range, and Denali Ultimate gets every available driver-assistance feature, including Super Cruise.

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

This is a moderate, selective buyer’s market, so you can shop with some leverage if you compare listings carefully.

• Deal availability: 35.9% of listings are priced as good or great deals.
• Inventory: There are 1,423 listings available.
• Price trend: Prices have softened 12.73% compared with last year.

If you find a listing below $50,420 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 $50,420 CAD sits slightly below last year's $57,773 CAD.

That softer pricing can help you buy more truck for the money today, but it also means future sellers may face a more competitive resale environment if prices stay under pressure. If you plan to own for several years, the current market gives you a better entry point than last year’s average. If you are thinking about resale later, buying well now matters more than usual.

Vehicles with solid owner satisfaction ratings, like this model year's 4.33/5, 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 Good rating from IIHS and a five-star overall rating 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 more advanced driver assistance, and Denali Ultimate gets 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 main caveat is that several advanced features are reserved for higher trims, so you will want to check carefully if you are shopping lower down the range.

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:

• 35.9% of listings are priced as good or great deals.
• Price trend: Prices have softened 12.73% compared with last year.
• Owners rate it 4.33/5 — a solid satisfaction signal.
• It adds the Denali Ultimate trim and a broad mix of luxury, tech, and capability.

Consider the 2022 if:

• At $48,515 CAD, the 2022 costs less than the current year's $50,420 CAD average.
• It brings a major makeover with bolder styling, a more lavish interior, and new high-grade trims.

Consider the 2024 if:

• At $55,623 CAD, the 2024 costs more than the current year's $50,420 CAD average.
• It broadens the truck’s appeal with strong versatility, easy-to-use technology, and a fuel-efficient diesel.

The bottom line: If you want the best mix of current pricing, strong owner satisfaction, and a well-equipped luxury-oriented pickup, the 2023 is the smart default. If you are more price-sensitive, the 2022 is worth a look for a lower entry cost, while the 2024 makes sense if you want to spend more for a newer model-year alternative.
