Used 2023 GMC Sierra 1500 for Sale nearScarborough, ON

How much does the 2023 GMC Sierra 1500 cost?

Prices have softened 12.95% compared to this time last year, making it a favourable time to shop this model year.

There are 1,407 listings available, which suggests you have a meaningful amount of inventory to compare.

Is the 2023 GMC Sierra 1500 a good car?

Generally — with a 4.33/5 user rating and an expert score of 7.83/10, the 2023 GMC Sierra 1500 lands as a strong choice if you want a full-size truck that leans into comfort and modern features. The standout strength is Safety at 9/10.

Owners consistently praise its stylish design, advanced technology, comfortable ride, and improved interior, and they also like the broad range of options. The truck’s appeal is especially clear if you want a work-capable pickup that can also feel richly equipped and modern.

The trade-offs are familiar for a feature-heavy truck: some drivers mention rising prices, limited availability of certain features like Super Cruise, and concerns about engine problems for long-term ownership. The expert view also notes that the cabin quality still trails the competition and that there can be too much tech for a truck.

Given the Sierra 1500’s broad capability and luxury-leaning positioning, it makes the most sense if you want a premium-feeling full-size pickup rather than a stripped-down work truck. With 34.7% of listings marked as good or great deals, there is still some room to shop selectively.

Is the 2023 GMC Sierra 1500 reliable?

Owners rate it 4.33/5, a solid signal of long-term satisfaction.

User feedback points to a truck that feels dependable in daily use, with many owners highlighting its comfortable ride, strong overall appeal, and improved interior as reasons they would count on it. The expert drive data also supports that impression by describing the Sierra as smooth, composed, and well suited to regular commuting as well as highway use.

The diesel powertrain is presented as lively and well matched to the 10-speed automatic, which helps it stay in its optimal power range. GMC also backs the Sierra 1500 with a five-year/100,000-kilometre powertrain warranty.

For used buyers, the main long-term ownership risk is that some owners have raised concerns about engine problems, so a careful service-history check matters.

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 and keeps the older, more intuitive infotainment layout, but it misses some basic conveniences such as a tilt and telescoping steering column. Higher trims add more comfort and luxury, while the Denali Ultimate brings nearly every feature optional on other trims.
• Powertrain: You can choose from 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 the 10-speed automatic is paired with every engine except the turbo-four.
• 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.
• Infotainment: The 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, plus Google-connected apps.
• Fuel efficiency: The Duramax turbo diesel with RWD is rated at 10.1 L/100 km city, 8.1 highway, and 9.2 combined. With 4WD, it rises to 10.7 city, 8.7 highway, and 9.8 combined. The turbo-four returns 12.7 city, 11.2 highway, and 12.0 combined, while the 5.3-litre V8 returns 14.3 city, 11.2 highway, and 12.9 combined. The 6.2-litre V8 with mud terrain tires returns 16.7 city, 14.0 highway, and 15.5 combined.

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 truck capability and the simpler 7-inch infotainment setup. It’s the least complicated choice, but you give up some everyday 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 climate control, a larger touchscreen, wireless smartphone integration, and more connectivity.
• Elevation: This trim builds on the SLE and makes certain options and packages available, so it suits you if you want a more personalised build without jumping straight to the pricier luxury trims.
• SLT: This is the comfort 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: Choose this if you want the off-road-oriented trim 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 option, 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 with 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 if you want nearly every feature optional on other trims, including full-grain leather, massaging front seats, a 12-speaker Bose system, 22-inch wheels, and the integrated Kicker sound system in the Multi-Pro tailgate.

The safety package expands as you move up the range, and the 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 looks like a moderate, selective buyer’s market, so you can shop carefully and still find worthwhile listings.

• Deal availability: 34.7% of listings are priced as good or great deals.
• Inventory: There are 1,407 listings available.
• Price trend: Prices have softened 12.95% compared with last year.

If you find a listing below $50,502 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 $50,502 CAD sits slightly below last year's $58,016 CAD.

That softer pricing can help you buy in at a more favourable point, but it also means future resale upside may depend more on trim, condition, and equipment than on broad market momentum. Higher-spec versions with desirable features may hold attention better, especially if they are well maintained and clearly documented.

For a future seller, the key takeaway is that the market has already adjusted downward, so strong presentation and service records matter more. A well-kept truck with the right equipment should still attract buyers, but you should not expect the same pricing environment that existed a year ago.

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 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 Super Cruise.

The main caveat is that some of the more advanced driver-assistance features are not standard across the range, so you may need to move up trims 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:

• 34.7% of listings are priced as good or great deals.
• Price trend: Prices have softened 12.95% compared with last year.
• Owners rate it 4.33/5 — a solid satisfaction signal.
• It adds the Denali Ultimate luxury focus and strong diesel performance.

Consider the 2022 if:

• At $48,480 CAD, the 2022 costs less than the current year's $50,502 CAD average.
• It brought a major makeover with bolder styling and a more lavish cabin.

Consider the 2024 if:

• At $55,779 CAD, the 2024 costs more than the current year's $50,502 CAD average.
• It broadens the truck’s appeal with a practical mix of work, off-road, and luxury capability.

The bottom line: If you want the best balance of price movement, inventory, and feature depth, the 2023 is the smart middle ground. If your priority is saving money, the 2022 is the better value play; if you want to spend more for a newer-year alternative, the 2024 is the natural step up.
