How much does the 2020 GMC Sierra 1500 cost?

Prices have softened 8.18% compared to this time last year, making it a favorable time to shop this model year.

There are 6,608 listings available, which suggests solid inventory for shoppers comparing trims and prices.

Is the 2020 GMC Sierra 1500 a good car?

Generally — you’re looking at a 4.28/5 user-rated truck with an 8.33/10 expert rating. The standout strength is Form and function at 10/10.

Owners consistently praise the spacious interior, advanced technology, strong performance, smooth ride, and overall value. The Sierra also fits a wide range of use cases, from everyday commuting to truck duty, and the AT4 trim broadens its appeal by blending comfort with capability.

The main trade-off is that advanced safety features are not standard, and the expert review also points to a rougher ride in the more off-road-focused setup. That means you may need to balance comfort, capability, and equipment level depending on how you plan to use it.

Good and great deals account for 31.5% of listings, which gives you some room to shop selectively.

Is the 2020 GMC Sierra 1500 reliable?

Owners rate it 4.28/5, a solid signal of long-term satisfaction.

Owner feedback highlights a truck that feels spacious, well-equipped, and strong in daily use, with many drivers appreciating its value and the range of available options. The expert review also emphasizes straightforward controls and a truck that’s built around practical, long-term usability.

At the same time, some owners reported engine-related concerns, including oil burning and recalls, so you should pay close attention to maintenance records and any repair history before you buy. For used shoppers, that makes a thorough pre-purchase inspection especially important if you want to reduce long-term ownership risk.

What should I look for when buying a used 2020 GMC Sierra 1500?

Accident-free inventory is solid at 75.9% — always verify the vehicle history report.

You should start with a history report, then prioritize a hands-on inspection of the truck’s condition, especially if you’re considering a higher-mileage example or one with a more complex option set. It’s also smart to focus on how the truck was used, since a work-focused life can leave different wear than a commuter or weekend-use truck.

Key things to evaluate:

• Trim level: The Base trim comes 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 adds an additional USB port, a WiFi hotspot, a larger 8-inch touchscreen, and remote keyless entry. The Elevation adds body-color exterior pieces, 20-inch wheels, heated front seats, remote engine start, and a heated steering wheel, while the SLT adds many of those comforts with more chrome styling. The AT4 is the off-road-oriented version with all-terrain tires and red tow hooks, and the Denali adds luxury touches like a head-up display, navigation, and wireless device charging.
• Powertrain: You get a choice of five engines, including a 4.3-liter V6, a 2.7-liter turbocharged 4-cylinder, a Duramax 3.0-liter turbodiesel, a 5.3-liter V8, and a 6.2-liter V8. The lineup gives you a wide spread of power and efficiency, and the 10-speed automatic is paired with rear-wheel drive or available 4WD.
• 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 forward-collision warning, lane-departure warning, automatic high beams, adaptive cruise control, blind-spot monitoring, lane-keeping assist, and rear cross-traffic alert. The AT4 test truck also came with a surround-view camera and front and rear parking sensors, but advanced safety features are not standard.
• Infotainment: The Base trim has a 7-inch touchscreen, while the SLE upgrades to an 8-inch touchscreen. The system is described as easy to use, with clear graphics, large icons, sensible menus, and tactile controls. Wireless device charging appears on the Denali, and the AT4 also featured 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 is the turbodiesel with rear-wheel drive at 23/30/26, while the 2.7-liter turbo returns 20/23/21 and the most efficient V8 is the 5.3-liter with rear-wheel drive at 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, and AT4.

Here's the short version:

• Base: This is the entry point, and it gives you the essentials without much extra flair. You get the V6, the 7-inch touchscreen, smartphone integration, Bluetooth, and LED headlights, so it works if you want a straightforward truck and plan to keep costs down.
• SLE: This is the trim that adds meaningful everyday convenience, including an 8-inch touchscreen, a WiFi hotspot, remote keyless entry, and an extra USB port. It also opens up more option packages, making it the best-value starting point for many shoppers.
• Elevation: This trim leans into style and comfort with body-color exterior details, 20-inch wheels, heated front seats, remote engine start, and a heated steering wheel. It’s a good fit if you want a more distinctive look and more standard comfort features.
• SLT: This is the trim CarGurus recommends, and it combines many of the nicer features with a more road-friendly setup. If you want a well-equipped truck without the AT4’s firmer off-road tuning, this is the one to focus on.
• Denali: This is the luxury play, with chrome accents, 22-inch wheels, a head-up display, navigation, and wireless charging. Choose it 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 suits you best if you want capability first and can live with a rougher ride on pavement.

Advanced safety features are not standard, so check carefully for the driver-assistance equipment you want on any trim.

Is now a good time to buy a used 2020 GMC Sierra 1500?

This is a moderate market for selective buyers, so you can shop with some leverage if you’re patient.

• Deal availability: 31.5% of listings are priced as good or great deals.
• Inventory: There are 6,608 listings available.
• Price trend: Prices have softened 8.18% compared with last year.
• Clean inventory: 75.9% of listings are accident-free.

If you find a listing below $33,120, 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 $33,120 sits slightly below last year's $36,072.

That softer pricing can help you buy more truck for the money today, but it also means future resale gains may be more limited if the market stays soft. If you’re planning to sell later, buying well matters more than usual because your exit price will likely track the broader market trend.

Trucks with strong owner satisfaction can still hold buyer interest, especially when they offer the kind of comfort, capability, and feature mix this one does. 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.

Is the 2020 GMC Sierra 1500 safe?

It earns an 8/10 safety score from our experts.

Available driver assistance features include forward-collision warning, lane-departure warning, automatic high beams, adaptive cruise control, blind-spot monitoring, lane-keeping assist, and rear cross-traffic alert. The AT4 test truck also came with a surround-view camera and front and rear parking sensors.

Advanced safety features are not standard, so you should verify exactly which driver-assistance systems are included on the truck you’re considering.

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:

• 31.5% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.9% — always verify the vehicle history report.
• Price trend: Prices have softened 8.18% compared with last year.
• Owners rate it 4.28/5 — a solid satisfaction signal.
• The 2020 blends SUV-like comfort with truck utility and easy-to-use technology.

Consider the 2019 if:

• At $31,048, the 2019 costs less than the current year's $33,120 average.
• It’s a thoroughly redesigned truck with a more updated feel.

Consider the 2021 if:

• At $34,819, the 2021 costs more than the current year's $33,120 average.
• It adds unique features like an optional carbon-fiber composite cargo bed.

The bottom line: If you want the best balance of price, inventory, and owner satisfaction, the 2020 is the sensible default. If you’re focused on saving money, the 2019 is the better value play; if you want a slightly newer truck with a few extra features and don’t mind paying more, the 2021 is worth a look.
