How much does the 2021 Cadillac XT6 cost?

Prices have softened 13.64% compared to this time last year, making it a favorable time to shop this model year.

There are 881 listings available, which gives you a solid pool to compare prices and equipment.

Is the 2021 Cadillac XT6 a good car?

The 2021 Cadillac XT6 is a compelling choice if you want a three-row luxury SUV with a polished feel, strong handling, and family-friendly space, though it asks you to accept some compromises. It earns a 3.67/5 user rating and a 7.5/10 expert rating.

The model scores 8/10 across Look and feel, Form and function, Technology, and Safety.

Cadillac’s crossover-style alternative to the larger Escalade brings refinement and confidence behind the wheel, plus a spacious third row and impressive technology. The trade-offs are clear: performance is fairly pedestrian, and the stereo is lacking.

For premium SUV shoppers who value a refined layout and usable third row more than outright excitement, the XT6 fits the brief well. 34.6% of listings are priced as good or great deals, so there is some room to shop selectively.

Is the 2021 Cadillac XT6 reliable?

The 2021 Cadillac XT6 is presented as a refined, confidence-inspiring luxury SUV, but it also carries some ownership caveats you should weigh carefully. The expert test drive data describes its performance as fairly pedestrian, and the vehicle’s weight and AWD hardware can make it feel less dynamic in everyday driving.

Its powertrain is described as smooth and easygoing, with the nine-speed automatic not struggling to find a gear. On the cost side, Cadillac’s maintenance and package structure can push the purchase price up quickly, so you should expect used ownership to reward careful option selection.

For long-term ownership, the main risk is that a used XT6 may deliver luxury comfort without feeling especially robust or low-maintenance if it has been heavily optioned or poorly cared for.

What should I look for when buying a used 2021 Cadillac XT6?

At 73% 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 thorough pre-purchase inspection, especially if the listing has been in an accident or carries a lot of added equipment. Focus on condition, service records, and whether the features you want are actually present on the trim you’re considering.

Key things to evaluate:

• Trim level: The Luxury trim is the most basic version, while Premium Luxury and Sport add more upscale equipment and, on those higher trims, standard blind-spot monitoring and rear cross-traffic alert. The base trim is the one most likely to leave you wanting more standard safety content.
• Powertrain: The base model uses a 2.0-liter turbo-four, while Premium Luxury and Sport use a 3.6-liter V6 with a nine-speed automatic. The V6 is the stronger choice if you want easier acceleration and a more relaxed feel.
• Safety package: The standard suite includes automatic emergency braking, forward-collision alert, following-distance indicator, lane-keep assist with lane-departure warning, a high-definition rearview camera, Safety Alert Seat, IntelliBeam headlights, and rear park assist. Premium Luxury and Sport add lane change alert with blind-spot monitoring and rear cross-traffic alert.
• Infotainment: You get an 8.0-inch touchscreen, wireless Apple CarPlay and Android Auto, infotainment user profiles, an eight-speaker Bose audio system, satellite radio, a WiFi hot spot, six USB ports, remote start, and Teen Driver monitoring. The screen is smaller than many rivals, so check whether that works for you.
• Fuel efficiency: The turbo-four is rated at 21 mpg city, 26 mpg highway, and 23 mpg combined with AWD, or 27 mpg highway with FWD. The V6 returns 19 mpg city, 26 mpg highway, and 21 mpg combined with FWD, while AWD lowers city and highway figures by one mpg each.

Which 2021 Cadillac XT6 trim should I buy?

The 2021 Cadillac XT6 is offered in 3 trim levels: Luxury, Premium Luxury, and Sport.

Here's the short version:

• Luxury: This is the entry point, and it gives you the XT6’s core three-row layout, standard sunroof, and the full standard safety suite. It makes sense if you want the XT6 experience at the lowest starting price, but it is also the trim most likely to feel light on premium extras.
• Premium Luxury: This is the best-value trim for many shoppers because it adds the stronger V6, available AWD, and more standard driver-assistance content than the base model. If you want the XT6’s upscale feel without jumping all the way to the Sport, this is the one to target.
• Sport: This trim is the most distinctive, with AWD-only availability and darker exterior accents that give it a more aggressive look. It suits you best if styling matters and you want the most assertive version of the XT6.

Premium Luxury and Sport also get lane change alert with blind-spot monitoring and rear cross-traffic alert as standard.

Is now a good time to buy a used 2021 Cadillac XT6?

This is a moderate, selective buyer’s market, so you can shop with some leverage if you know what you want.

• Deal availability: 34.6% of listings are priced as good or great deals.
• Inventory: There are 881 listings available.
• Price trend: Prices have softened 13.64% compared with last year.
• Clean inventory: 73.0% of listings are accident-free.

If you find a listing below $26,559, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Cadillac XT6's resale value?

The current average of $26,559 sits slightly below last year's $30,755.

That drop suggests the XT6 has softened in the used market, which can help you buy in at a more favorable price today. If you plan to sell later, you should expect resale value to depend heavily on trim, condition, and whether the vehicle has a clean history.

Because the market has moved down, a well-kept XT6 with desirable equipment may hold up better than a heavily optioned example that is harder to price competitively. For you, that means buying carefully now can reduce the risk of taking a bigger hit later.

Is the 2021 Cadillac XT6 safe?

The 2021 Cadillac XT6 earns five-star ratings in frontal crash and four-star ratings in rollover from NHTSA.

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

All Cadillac XT6 models come with automatic emergency braking, forward-collision alert, following-distance indicator, lane-keep assist with lane-departure warning, a high-definition rearview camera, Safety Alert Seat, IntelliBeam headlights, and rear park assist. Premium Luxury and Sport models also add lane change alert with blind-spot monitoring and rear cross-traffic alert as standard.

One caveat is that the lane-keep assist and lane-departure warning systems can be slow to recognize lane markings, so you should test them carefully on your drive.

Should I buy a 2021 Cadillac XT6 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 34.6% of listings are priced as good or great deals.
• At 73% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 13.64% compared with last year.
• The 2021 XT6 pairs strong handling with a spacious third row and impressive technology.

Consider the 2020 if:

• At $24,758, the 2020 costs less than the current year's $26,559 average.
• It offers roomy, stylish luxury with accessible pricing.

Consider the 2022 if:

• At $29,767, the 2022 costs more than the current year's $26,559 average.

The bottom line: If you want the best mix of price and features, the 2021 is the smart middle ground. If your budget is tighter, the 2020 can save you money, while the 2022 is worth a look if you want to spend more for a newer-feeling package.
