What should I look for when buying a used Audi A6?

Across all model years, accident-free inventory is solid at 75.3% — always verify the vehicle history report.

Older model years carry meaningfully higher accident rates, so always verify the vehicle history report on pre-2020 models.

Key things to evaluate:

• Safety package: adaptive cruise control, forward-collision warning, automatic emergency braking, rear cross-traffic alert, blind-spot monitors, traffic-sign recognition, parking sensors, and lane-departure warning
• Infotainment: standard wireless Apple CarPlay and Android Auto
• Fuel efficiency: The A6’s EPA-rated 23 mpg combined (20 mpg city, 29 mpg highway) isn’t bad for a generously-proportioned sedan with a V6 and AWD.

Which Audi A6 trim should I buy?

The 2026 Audi A6 offers these trims:

• Premium: The entry trim brings the turbocharged 3.0-liter V6, seven-speed dual-clutch transmission, standard quattro all-wheel drive, a 11.9-inch digital instrument cluster, a 14.5-inch touchscreen, and standard wireless Apple CarPlay and Android Auto. It suits you if you want the core A6 experience with strong standard equipment.
• Premium Plus: This trim adds adaptive cruise assist with automated lane centering, a 360-degree camera system, and a park-assist system, making it the best-value choice for shoppers who want more convenience and driver-assistance tech.
• Prestige: The top trim adds adaptive air suspension, and it can be paired with the Sport Plus Package for rear-axle steering, a sport rear differential, and a lower ride height. It suits you if you want the most advanced chassis and comfort hardware.
• Prestige with S Line Black Optic Package: This version adds a sportier front bumper, blacked-out trim, and dark chrome 20-inch wheels for a sharper appearance.

What Audi A6 do most buyers choose?

The Audi A6 years with the most listings are 2025, 2018, and 2023.

Higher-volume years tend to draw more shoppers because they usually offer a broader mix of prices, trims, and equipment. That gives you more chances to find the right balance of value and features.

What is the Audi A6's resale value?

Most model years in the table are down by double digits, which points to strong value for used buyers. The steepest drops are concentrated in newer years, while older examples show smaller declines. That pattern can make recent model years especially attractive if you want newer features at a lower price than before.

The 2016, 2014, and 2015 model years have held their value best, with the smallest year-over-year price changes.

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

Buy now if:

• Price trend: The 2025 model is at −14.05% versus a year ago, and the 2024 model is at −16.56%.
• Deal availability: The 2025 model has 36.2% good and great deals, and the 2024 model has 38.6%.
• Sweet-spot year: The 2025 model has the most listings at a current average price of $45,432. The Audi A6 offers a refined cabin and a calm, upscale character that make it easy to live with every day.

Consider waiting if:

• Powertrain/efficiency: The A6’s EPA-rated 23 mpg combined (20 mpg city, 29 mpg highway) isn’t bad for a generously-proportioned sedan with a V6 and AWD.
• Tech: The latest MMI (Multimedia Interface) infotainment system waters things down with layouts that are both oversimplified and hard to interpret, and Audi’s improved voice recognition system helps to some extent, as do standard wireless Apple CarPlay and Android Auto.
• 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 2025 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for the next model year's inventory to build up.
