The current average of $22,385 sits slightly below last year's $24,917.

That price movement suggests the market has cooled, which can help you buy more carefully now but may also limit short-term upside if you plan to resell soon.

Should I buy a 2021 Cadillac XT4 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:

• 35.3% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.2% — always verify the vehicle history report.
• Price trend: Prices have softened 10.16% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.

Consider the 2020 if:

• At $19,829, the 2020 costs less than the current year's $22,385 average.
• It offers a small footprint with broad appeal and easy-to-use technology.

The bottom line: If you want the stronger current-market balance of price, inventory, and owner satisfaction, the 2021 is the better default choice. If your priority is spending less up front, the 2020 is the more budget-friendly path and may be the better fit.
