You should still run a vehicle history report and prioritize a pre-purchase inspection, especially if the listing price looks unusually attractive. Focus on overall condition, maintenance records, and any signs of prior bodywork or deferred upkeep.

Is now a good time to buy a used 2021 Audi RS Q8?

What is the 2021 Audi RS Q8's resale value?

The current average of $75,652 sits slightly below last year's $77,657.

That softer pricing can help you buy at a more favorable entry point, but it also means future resale gains may be more limited if the market stays soft. If you plan to sell later, buying well today matters even more because your eventual trade-in or private-sale value will depend heavily on how much room you leave between purchase price and market average.

Vehicles with strong owner satisfaction ratings, like this model year's 4.5/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Audi RS Q8 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:

• 26.4% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 94.5% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 2.58% compared with last year.
• Owners rate it 4.5/5 — a strong satisfaction signal.

The bottom line: If you want this body style and can find a well-kept example at a competitive price, the 2021 is the primary path to consider because the market offers decent deal availability and strong owner satisfaction. If you’re especially price-sensitive, keep an eye on nearby model years and compare condition, history, and asking price closely so you can choose the best value rather than just the newest badge.
