CarGurus Analysis: 2025 BMW X6

Summary
With 545 currently listed for sale and an average price of $68,054, 39.8% of 2025 BMW X6 listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2025 BMW X6 5 / 5 stars.
91.6% of 2025 BMW X6 listings on CarGurus are accident free.
Why it stands out
The 2025 BMW X6 stands out because it still leans into the original crossover-coupe idea that made the model distinctive in the first place: a low, fastback shape with a sportier attitude than a conventional SUV. In this generation, BMW gave it a sleeker roofline, a lower stance, huge wheels, and a more aggressive body kit, along with wider taillights, enlarged fender flares, and a wider front grille with optional backlighting. It also grew slightly in size, which helped support the X6’s more substantial road presence.
The 2025 model also benefits from the X6’s emphasis on performance hardware and upscale equipment. Standard features include a panoramic moonroof, two 12.3-inch displays running iDrive 7, navigation, adaptive LED headlights, blind-spot monitors, forward emergency braking, lane-departure warning, heated front seats, and a sports leather steering wheel. The six-cylinder version added a mild hybrid setup for 2021, and the 2024 refresh brought updated lighting with sequential turn signals, new fascias and bumpers, new wheels, more power for the xDrive40i, and an optional Highway Assistant for hands-free driving. For 2025, BMW updated smartphone apps, navigation, digital keys, and the Highway Assistant.
That said, the X6 remains a style-first luxury SUV, so its compromises are part of the package. The buying guide notes poor cargo space and poor fuel economy among its drawbacks, and the model’s appeal is strongest for shoppers who value its design, strong powertrains, and high level of equipment more than maximum practicality.

Is the 2025 BMW X6 a good car?
Yes — the 5/5 user rating points to strong owner satisfaction. The 2025 BMW X6 stands out for its distinctive crossover-coupe shape, sportier attitude than a conventional SUV, and upscale equipment. It also leans into performance hardware and a high level of standard technology, while the tradeoff is that it remains a style-first luxury SUV with poor cargo space and poor fuel economy. With 40.7% of listings marked as good or great deals, you have a decent chance of finding a compelling offer.
Is the 2025 BMW X6 reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The 2025 BMW X6 is presented as a well-equipped luxury SUV with a strong emphasis on performance and technology, which can support confidence in day-to-day ownership. Its appeal is strongest if you value its design and equipment more than maximum practicality. For used buyers, the main long-term ownership risk is that its style-first packaging can make compromises more noticeable over time.
What should I look for when buying a used 2025 BMW X6?
Accident-free inventory is excellent at 91.6% — clean inventory, standard diligence applies.
You should still run a vehicle history report and verify that the listing matches the car’s condition and equipment. Prioritize a pre-purchase inspection, especially if you want to confirm the condition of the drivetrain, electronics, and luxury features. Focus on signs of wear that matter most on a premium SUV, including interior condition, wheel and tire condition, and evidence of prior bodywork.
Is now a good time to buy a used 2025 BMW X6?
Yes — this looks like a buyer-friendly market if you are ready to compare listings carefully.
- Deal availability: 40.7% of listings are priced as good or great deals.
- Inventory: There are 545 listings available.
- Price trend: Prices have softened 9.69% compared with last year.
- Clean inventory: 91.6% of listings are accident-free.
If you find a listing below $68,070, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2025 BMW X6's resale value?
The current average of $68,070 sits slightly below last year's $75,377.
That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, that also means resale performance will depend heavily on how well the vehicle is maintained and how desirable its configuration remains. A clean history and strong presentation should matter more when it comes time to sell.
Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.
Should I buy a 2025 BMW X6 or consider a different year?
If you're weighing the 2025 against nearby model years, here's how to think about it:
Choose the 2025 if:
- 40.7% of listings are priced as good or great deals.
- Accident-free inventory is excellent at 91.6% — clean inventory, standard diligence applies.
- Price trend: Prices have softened 9.69% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
The bottom line: If you want the freshest version of this style-first luxury SUV and you value strong owner satisfaction, the 2025 is the primary path to consider. If your priority is stretching your budget further, a nearby model year may be the better secondary path, especially if you can find a cleaner or better-priced example with the equipment you want.
