Is the 2023 Audi A6 a good car?

The 2023 Audi A6 stands out as a midsize luxury sedan that blends understated style with a strong technology focus. Audi’s conservative design helps it age well, and the A6 has long been known for offering premium feel without looking flashy. For you, that means a sedan that can feel current without trying too hard, especially if you value a refined cabin and a sophisticated but restrained personality.

It also brings a major step forward in technology, with digital interfaces, standard Apple CarPlay and Android Auto, dual screens, lots of connectivity, and semi-autonomous capability. Standard quattro all-wheel drive across the lineup adds all-weather confidence, and the blend of comfort and sportiness gives it broad appeal for luxury shoppers.

With 31.6% of listings marked as good or great deals, you have a meaningful share of the market to shop from if you want value as well as features.

Is the 2023 Audi A6 reliable?

The 2023 Audi A6 is described as a refined luxury sedan with a high-end interior, standard all-wheel drive, and a strong technology package. Its conservative design and premium feel suggest a car built to satisfy buyers who want comfort and capability in the same package.

At the same time, the A6’s front-wheel-drive bias and disappointing fuel economy point to a few tradeoffs you should keep in mind as a used buyer. For long-term ownership, that means you should be especially attentive to maintenance history and overall condition so you can avoid expensive surprises later.

What should I look for when buying a used 2023 Audi A6?

Accident-free inventory is excellent at 91% — clean inventory, standard diligence applies.

You should still run a history report on any car you’re seriously considering, even if the listing looks clean. Prioritize a pre-purchase inspection, especially on a luxury sedan with advanced electronics and all-wheel drive, and focus on signs of wear in the cabin, tires, brakes, and service records.

Is now a good time to buy a used 2023 Audi A6?

What is the 2023 Audi A6's resale value?

The current average of $34,305 sits slightly below last year's $35,162.

That price movement suggests the market has eased a bit, which can help you as a buyer today but may also mean slower appreciation if you plan to resell later. If you buy well now, you may have a better chance of limiting depreciation pressure over your ownership period. For a future seller, the key will be keeping mileage, condition, and service history strong enough to stand out in a market that has already softened.

Should I buy a 2023 Audi A6 or consider a different year?

If you're weighing the 2023 against nearby model years, here's how to think about it:

Choose the 2023 if:

• 31.6% of listings are priced as good or great deals.
• Accident-free inventory is excellent at 91% — clean inventory, standard diligence applies.
• Price trend: Prices have softened 2.44% compared with last year.

The bottom line: The 2023 is the right path if you want the A6’s refined cabin, standard all-wheel drive, and tech-forward feel in a year that’s showing softer pricing and decent deal availability. If you’re especially price-sensitive, you can also compare nearby years to see whether a slightly older example gives you a lower entry point without giving up the core A6 formula.
