CarGurus Analysis: 2020 GMC Sierra 1500

Summary
With 468 currently listed for sale and an average price of $37,919 CAD, 33.5% of 2020 GMC Sierras for sale on CarGurus are rated as good or great deals.
Favourably reviewed: Owners rated the 2020 GMC Sierra 1500 4.28 / 5 stars.
100.0% of 2020 Sierra 1500 models on CarGurus are accident free.
Why it stands out
The 2020 GMC Sierra 1500 stands out as a full-size pickup that leans into a more upscale personality than many rivals. It sits in the fifth generation, which was introduced for the 2019 model year, and GMC’s positioning gives it near-luxury cabin quality without many frills or embellishments. For shoppers, that means the Sierra aims to combine strong capability with a more polished feel, along with good connectivity features and trim levels that range from practical to premium.
For 2020, the Sierra 1500 is described as a reliable choice, and this model year in particular earned lots of satisfied customers. The broader lineup offers a wide spread of powertrains, including a 2.7-litre turbocharged four-cylinder, a 4.3-litre V6, a 5.3-litre V8, a 6.2-litre V8, and a 3.0-litre inline-six Duramax turbodiesel, with rear- and four-wheel drive available and six-, eight-, and 10-speed automatic transmissions depending on engine. The trim range is also broad, from Pro and SLE through Denali, Denali Ultimate, AT4, and AT4X, so buyers can choose between luxury styling, rugged off-road hardware, and added comfort features such as the AT4X’s 16-way power heated and ventilated front seats with a massage feature.
A few standout features help define the Sierra’s appeal. The 2022 refresh brought updated styling, better infotainment functionality, and availability of Super Cruise, while the MultiPro tailgate adds practical versatility with its split-gate design. At the same time, the Sierra can be expensive even used, and the engine and trim lineup can be overwhelming, so it rewards buyers who know exactly which mix of capability, comfort, and equipment they want.

Absolutely stunning vehicle. Pure luxury pick-up truck. Serious power, w/a 6.2L V8 engine; smooth, wonderful ride, lots of driver convenience & safety features; comfortable seating, roomy cab interior....I could go on. GMC has left nothing out of their Sierra Denali line. Beautiful truck - everyone Ive talked to feels the same. Commanding presence on the road. Tops Dodge Ram & Ford models, in my opinion. I have a 2020 model. The 2023 model tops even THAT!!!

There are 472 listings available, which gives you a decent amount of choice if you're comparing trims and equipment.
Is the 2020 GMC Sierra 1500 a good car?
Generally — the 4.28/5 user rating suggests you can feel reasonably confident shopping this truck. Owners consistently praise the spacious interior, advanced technology, strong performance, smooth ride, and overall value, which fits a full-size pickup that aims for a more upscale feel. For you, that means the Sierra makes the most sense if you want capability with a more polished cabin and a wide range of trims and features to choose from. 32.0% of listings are priced as good or great deals, which gives you some room to find a competitive example.
Is the 2020 GMC Sierra 1500 reliable?
Owners rate it 4.28/5, a solid signal of long-term satisfaction.
The owner feedback points to a truck many people have found dependable and trouble-free enough to recommend, with satisfaction tied to its strong performance and broad usefulness. At the same time, some owners reported engine-related concerns, including oil burning and recalls, so you should pay close attention to service records and any repair history. For a used buyer, that means the long-term ownership risk is manageable, but only if you verify maintenance and inspect carefully before you commit.
Is now a good time to buy a used 2020 GMC Sierra 1500?
This looks like a moderate, selective buyer’s market, so you can shop patiently and still find worthwhile listings.
- Deal availability: 32.0% of listings are priced as good or great deals.
- Inventory: There are 472 listings available.
- Price trend: Prices have softened 13.24% compared with last year.
If you find a listing below $36,362 CAD, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2020 GMC Sierra 1500's resale value?
The current average of $37,829 CAD sits slightly below last year's $43,600 CAD.
That drop suggests the market has already adjusted downward, which can help you buy more affordably now but may also limit upside if you plan to resell soon. If you purchase at a strong price, you reduce the risk of taking a bigger hit later. The truck’s broad appeal and premium positioning can still support demand, especially for well-equipped examples in good condition.
Vehicles with solid owner satisfaction ratings, like this model year's 4.28/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2020 GMC Sierra 1500 or consider a different year?
If you're weighing the 2020 against nearby model years, here's how to think about it:
Choose the 2020 if:
- 32.0% of listings are priced as good or great deals.
- Price trend: Prices have softened 13.24% compared with last year.
- Owners rate it 4.28/5 — a solid satisfaction signal.
Consider the 2021 if:
- At $40,138 CAD, the 2021 costs more than the current year's $37,829 CAD average.
- It adds an optional carbon-fibre composite cargo bed.
The bottom line: You should start with the 2020 if value matters most, because it offers a lower average price and meaningful deal availability. If you want the newer year’s added features and are comfortable paying more, the 2021 is the better secondary path.
