What should I look for when buying a used 2019 Audi A6?

At 69.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a thorough pre-purchase inspection, especially if the car has had any prior damage. Focus on bodywork quality, panel alignment, tire wear, brake feel, and whether the cabin electronics and driver-assistance features operate as intended.

Key things to evaluate:

• Trim level: Premium Plus is the recommended value pick because it adds the features you’re most likely to want without pushing you into the highest-priced trim. Premium Plus trim includes Audi Virtual Cockpit, a Bang & Olufsen audio system, a larger 10.1-inch navigation display, and a surround-view camera with Virtual 360 technology. Prestige adds more equipment, but the content suggests you may not need the extra spend unless you specifically want the top-end features.
• Powertrain: The car uses a creamy smooth turbocharged 3.0-liter V6 with 335 horsepower and 369 pound-feet of torque, paired with a 7-speed S tronic automated manual transmission and Quattro Ultra all-wheel drive. It also uses a standard 48-volt mild-hybrid system that helps reduce engine load and supports fuel-saving coasting behavior.
• Safety package: Pre Sense systems are standard up front and available for the rear. With the Driver Assistance Package on Premium Plus or Prestige, you get adaptive cruise control with traffic-jam assist and turn assist, active lane assist with emergency assist, intersection assistant, and traffic-sign recognition. Prestige also adds HD Matrix LED headlights with automatic high-beam activation, while the optional night-vision assistant with pedestrian detection is exclusive to Prestige.
• Infotainment: The A6 uses two touchscreen displays, Audi’s latest MMI system, a 10.1-inch navigation display, wireless-style haptic feedback inputs, a surround-view camera with 360 Virtual View technology, and Audi Virtual Cockpit digital instrumentation. The system also includes strong natural-voice recognition and handwriting recognition.
• Fuel efficiency: The expert review notes 22.9 mpg on a test loop and says the EPA expected 25 mpg.

Which 2019 Audi A6 trim should I buy?

The 2019 Audi A6 is offered in 3 trim levels: Premium, Premium Plus, Prestige.

Here's the short version:

• Premium: This is the entry point, but the content makes clear that the more desirable equipment starts showing up as you move up the range. If you want the lowest starting price and are comfortable keeping things simpler, this is the trim to consider.
• Premium Plus: This is the best-value trim. It adds Audi Virtual Cockpit, a Bang & Olufsen audio system, a larger 10.1-inch navigation display, and a surround-view camera with Virtual 360 technology, giving you the features most shoppers will actually notice every day.
• Prestige: Choose this if you want the most complete version of the A6. It adds HD Matrix LED headlights with automatic high-beam activation and is the only trim that can get the optional night-vision assistant with pedestrian detection.

Audi’s safety and driver-assistance features are more unusual and sophisticated on Premium Plus and Prestige, especially when you add the Driver Assistance Package.

Is now a good time to buy a used 2019 Audi A6?

This is a moderate market for selective buyers, so you can shop with some leverage if you’re patient.

• Deal availability: 35.6% of listings are priced as good or great deals.
• Inventory: There are 578 listings available.
• Price trend: Prices have softened 11.50% compared with last year.
• Clean inventory: 69.9% of listings are accident-free.

If you find a listing below $21,951, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2019 Audi A6's resale value?

The current average of $22,011 sits slightly below last year's $24,871.

That price movement suggests the market has already adjusted downward, which can help you as a buyer today but may temper what a future seller can expect. If you buy at the right price and keep the car in strong condition, you’ll be better positioned to limit depreciation pain later.

Vehicles with strong owner satisfaction ratings, like this model year's 4.89/5, tend to retain buyer demand, which supports resale value over time.

Is the 2019 Audi A6 safe?

The 2019 Audi A6 earns a 10/10 safety score from our experts.

Audi offers a long list of driver-assistance and collision-avoidance systems, with the more unusual and sophisticated features reserved for Premium Plus and Prestige trim levels. Pre Sense systems are standard up front and available for the rear, and the Driver Assistance Package adds adaptive cruise control with traffic-jam assist and turn assist, active lane assist with emergency assist, intersection assistant, and traffic-sign recognition.

Prestige trim also adds HD Matrix LED headlights with automatic high-beam activation, and the optional night-vision assistant with pedestrian detection is exclusive to Prestige. The safety content emphasizes that these systems work subtly in the background, which should make them easier for you to keep engaged during everyday driving.

Should I buy a 2019 Audi A6 or consider a different year?

If you're weighing the 2019 against nearby model years, here's how to think about it:

Choose the 2019 if:

• 35.6% of listings are priced as good or great deals.
• At 69.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.50% compared with last year.
• Owners rate it 4.89/5 — a strong satisfaction signal.
• The redesigned 2019 A6 brings a completely new approach to MMI, a light-electrified hybrid powertrain, and more sophisticated driver-assistance technologies.

The bottom line: If you want the newer-generation A6 with the strongest tech story, the 2019 is the one to target. It gives you the redesigned cabin, the mild-hybrid V6, and the advanced safety and infotainment setup that define this model year. If you’re mainly focused on stretching your budget, a nearby year may still make sense, but the 2019 is the better pick when you want the most modern version of the car.
