Should I buy a used Audi A6 now or wait for the next model?

Buy now if:

• Price trend: The 2025 model is at −13.16% versus a year ago, and the 2024 model is at −19.9%.
• Deal availability: The 2025 model has 33.1% good and great deals, and the 2024 model has 35%.
• Sweet-spot year: The 2024 model has the most listings at a current average price of $30,657. The Audi A6 offers a premium cabin with understated styling that ages well.

Consider waiting if:

• Powertrain/efficiency: The last engine standing is a turbocharged 3.0-liter V6, connected to a seven-speed dual-clutch transmission and standard quattro all-wheel drive (AWD). This is the same engine used in the S5 sedan, and it makes the same 362 horsepower and 406 pound-feet of torque here.
• Tech: A standard 11.9-inch digital instrument cluster and 14.5-inch touchscreen flank the driver, and an optional 10.9-inch front-passenger touchscreen is available.
• Safety: A park-assist system, adaptive cruise assist (which adds automated lane centering) and a 360-degree camera system are also standard on the Premium Plus and Prestige trim levels.
• Starting price: Pricing starts at $65,395 for the base A6 Premium (all prices include a $1,295 destination charge).

If you're buying used today, the 2024 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for 2028 inventory to mature.
