CarGurus Analysis: 2020 GMC Sierra 1500
overall

Summary
With 6,836 currently listed for sale and an average price of $32,312, 32.7% of 2020 GMC Sierra 1500 listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2020 GMC Sierra 1500 4.3 / 5 stars and CarGurus experts gave it an 8.3 / 10.
73.8% of 2020 GMC Sierra 1500 listings on CarGurus are accident free.
Why it stands out
The 2020 GMC Sierra 1500 stands out because it blends pickup utility with the kind of comfort and convenience many shoppers now expect from SUVs and crossovers. The truck’s AT4 trim is described as comfortable but also capable, and the overall impression is that this Sierra is aimed at buyers who want a truck that can handle both daily driving and worksite duties. It also reflects how far pickups have come, with modern cabins that are more comfortable than the old-school truck interiors many buyers remember.
Its strengths include multiple powertrain options and easy-to-use technology, both of which make it appealing to a wide range of buyers. The Sierra also benefits from utility-minded touches such as cargo-management tools, side steps, and bed steps, which add practicality without changing the truck’s basic formula. Owners also praise the spacious interior, advanced technology, strong performance, and smooth ride.
The main limitation noted in the data is that advanced safety features are not standard. That means the 2020 GMC Sierra 1500 can feel well equipped and versatile, but shoppers who want a fuller safety package may need to pay close attention to equipment levels.

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!!!

Is the 2020 GMC Sierra 1500 a good car?
Generally — the 2020 GMC Sierra 1500 earns 4.3/5 from owners and 8.3/10 from our experts. The standout strength is Form and function at 10/10.
Owners consistently praise the spacious interior, advanced technology, strong performance, smooth ride, and the variety of options available. That lines up well with the truck’s use case as a pickup that can handle daily driving and worksite duties while still feeling comfortable and modern.
The main trade-offs are that advanced safety features are not standard, and some drivers note issues with engine performance, including oil burning and recalls. With the Sierra’s blend of utility and comfort, it makes the most sense if you want a truck that feels more polished than old-school pickups, but you should pay close attention to equipment levels.
The market shows 33.0% of listings as good or great deals, which points to a reasonably favorable shopping environment.
Is the 2020 GMC Sierra 1500 reliable?
Owners rate it 4.3/5, a solid signal of long-term satisfaction.
Owner feedback points to a truck that many drivers find dependable and satisfying over time, with praise for its strong performance, spacious cabin, and overall value. The review summary also suggests many owners appreciate the truck’s variety of options and the sense that it can serve as a long-term daily driver.
The expert evaluation also emphasizes that modern trucks like this one are built to be useful, comfortable, and capable, with utility-minded features that support everyday ownership. The cost-effectiveness commentary reinforces that GMC designed this truck for real-world use, from commuting to hauling.
For used buyers, the main long-term ownership risk is that reported engine issues and recalls can turn into expensive headaches if you skip a careful inspection.
What should I look for when buying a used 2020 GMC Sierra 1500?
At 73.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if the truck has been used for towing, off-road driving, or heavy work. Focus on condition, maintenance records, and any signs of wear that could point to harder-than-average use.
Key things to evaluate:
- Trim level: The Base truck comes decently equipped with a V6 engine, a 7-inch touchscreen, Apple CarPlay, Android Auto, Bluetooth connectivity, a USB port, and LED “light blade” headlights. Moving up to the SLE trim adds an additional USB port, a WiFi hotspot, a larger 8-inch touchscreen, and remote keyless entry. The Elevation adds body-color exterior touches, 20-inch wheels, heated front seats, remote engine start, and a heated steering wheel. The SLT adds many of those comforts with more classic chrome styling. The AT4 is the off-road-oriented version with all-terrain tires, red tow hooks, black leather with brown accents, skid plates, upgraded suspension components, hill-descent control, and Rancho off-road shocks. The Denali adds chrome accents, 22-inch wheels, a head-up display, navigation, and wireless device charging.
- Powertrain: The Sierra offers five engines, starting with a 4.3-liter V6 making 285 horsepower and 305 pound-feet of torque. Other options include a 2.7-liter turbocharged 4-cylinder, a Duramax turbodiesel 3.0-liter 6-cylinder, a 5.3-liter V8, and a 6.2-liter V8. Power goes through an automatic transmission to rear-wheel drive or available 4-wheel drive, and the 10-speed transmission uses a column shifter.
- Safety package: Standard safety features include a reversing camera, traction control, and a full array of front- and side-impact airbags. Available driver assistance features include a vivid surround-view camera, front and rear parking sensors, forward-collision warning, lane-departure warning, automatic high beams, adaptive cruise control, blind-spot monitoring, lane-keeping assist, and rear cross-traffic alert. Advanced safety features are not standard, so trim and option content matter.
- Infotainment: The Base truck has a 7-inch touchscreen, while the SLE gets an 8-inch touchscreen. The system includes Apple CarPlay, Android Auto, Bluetooth connectivity, and a sensible menu layout with clear graphics and tactile controls. The AT4 also features a head-up display, wireless charging, and multiple USB ports and outlets.
- Fuel efficiency: The AT4 returns 15 mpg city, 19 highway, and 17 combined. The most efficient version of the Sierra 1500 is the turbodiesel with rear-wheel drive, returning 23/30/26. The 2.7-liter turbo returns 20/23/21, while the most efficient V8 is the 5.3-liter with rear-wheel drive, returning 17/24/20.
Which 2020 GMC Sierra 1500 trim should I buy?
The 2020 GMC Sierra 1500 is offered in 6 trim levels: Base, SLE, Elevation, SLT, Denali, AT4.
Here's the short version:
- Base: This is the most affordable way into the Sierra 1500, and it already gives you a V6, a 7-inch touchscreen, Apple CarPlay, Android Auto, Bluetooth, a USB port, and LED headlights. It makes sense if you want the essentials and plan to keep the truck simple.
- SLE: This trim adds an extra USB port, a WiFi hotspot, an 8-inch touchscreen, and remote keyless entry, making it the best-value choice for many shoppers. It gives you a more modern cabin without jumping too far up the price ladder.
- Elevation: This one is for you if you want a more distinctive look, plus heated front seats, remote engine start, and a heated steering wheel. It adds style and comfort, but it is more about appearance and convenience than maximum value.
- SLT: CarGurus recommends the SLT trim. It keeps many of the comfort features you want while offering a more road-friendly setup with more compliant tires and suspension.
- Denali: This is the luxury-focused choice, with chrome accents, 22-inch wheels, a head-up display, navigation, and wireless charging. It suits you if you want the most upscale Sierra experience.
- AT4: This is the off-road-oriented trim, with all-terrain tires, red tow hooks, skid plates, upgraded suspension components, hill-descent control, and Rancho off-road shocks. It is the right pick if you want capability to match the rugged styling.
Advanced safety features are not standard, so check equipment carefully on any trim you consider.
Is now a good time to buy a used 2020 GMC Sierra 1500?
The market looks moderately favorable if you are a selective buyer.
- Deal availability: 33.0% of listings are priced as good or great deals.
- Inventory: There are 6,806 listings available.
- Price trend: Prices have softened 8.73% compared with last year.
- Clean inventory: 73.9% of listings are accident-free.
If you find a listing below $32,289, 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 $32,289 sits slightly below last year's $35,379.
That decline suggests the truck has already absorbed some depreciation, which can help future sellers if they buy at the right price. A softer market today can also mean less upside if you overpay now, so condition and trim matter a lot.
If you choose a well-equipped example with strong maintenance history, you may have a better chance of holding value than with a truck that shows wear or missing features. Demand should remain supported by the Sierra’s broad appeal, but resale will still depend on how clean and desirable your specific truck is.
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 2020 GMC Sierra 1500 safe?
The 2020 GMC Sierra 1500 earns an 8/10 safety score from our experts.
Standard safety features include a reversing camera, traction control, and a full array of front- and side-impact airbags. Available driver assistance features include forward-collision warning, lane-departure warning, automatic high beams, adaptive cruise control, blind-spot monitoring, lane-keeping assist, rear cross-traffic alert, a surround-view camera, and front and rear parking sensors. Advanced safety features are not standard, so you should verify the exact equipment on any used listing.
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:
- 33.0% of listings are priced as good or great deals.
- At 73.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 8.73% compared with last year.
- Owners rate it 4.3/5 — a solid satisfaction signal.
- It blends pickup utility with SUV-like comfort and easy-to-use technology.
Consider the 2019 if:
- At $30,554, the 2019 costs less than the current year's $32,289 average.
- It was completely redesigned and improved across the board.
Consider the 2021 if:
- At $33,739, the 2021 costs more than the current year's $32,289 average.
- It adds unique features like an optional carbon-fiber composite cargo bed.
The bottom line: The 2020 is a strong choice if you want a comfortable, versatile Sierra with broad appeal and a softer price than the next model year. If you are more price-sensitive, the 2019 can save you money, while the 2021 makes sense if you want the newer-year features and are willing to pay more.
