Should I buy a 2021 BMW X6 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:

• 35.0% of listings are priced as good or great deals.
• Accident-free inventory is solid at 82.7% — always verify the vehicle history report.
• Price trend: Prices have softened 10.65% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line: If you want the strongest mix of current pricing pressure, decent inventory, and positive owner feedback, the 2021 is the primary year to focus on. If you're especially price-sensitive, you can also compare nearby years to see whether a lower asking price outweighs the 2021's current market balance.
