Is the 2023 Audi S4 a good car?

The 2023 Audi S4 stands out as a compact performance sedan that blends strong acceleration, standard all-wheel drive, and a polished cabin without becoming overly flashy. It offers more power and equipment than the regular A4, and it is also described as less exciting than some rivals such as the BMW M340i and Mercedes-AMG C43.

For you, that means the S4 makes the most sense if you want a quick luxury sedan that still feels usable every day. 34.2% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2023 Audi S4 reliable?

The 2023 Audi S4 is described as decently reliable for this generation, and it pairs that with a polished driving experience and useful tech. It also benefits from a well-equipped interior and standard all-wheel drive, which adds to its everyday appeal.

For used buyers, the main long-term ownership risk is that Audis typically require more maintenance than rival brands, so condition and service history matter a lot.

What should I look for when buying a used 2023 Audi S4?

Accident-free inventory is solid at 85.1% — always verify the vehicle history report.

You should prioritize a history report first, then focus on a pre-purchase inspection so you can catch any hidden issues before they become expensive. Pay close attention to overall condition, maintenance records, and whether the car has the equipment you want, since some features were optional on earlier examples.

Is now a good time to buy a used 2023 Audi S4?

This is a moderate market, so you can be selective without expecting every listing to be a bargain.

• Deal availability: 34.2% of listings are priced as good or great deals.
• Inventory: There are 114 listings available.
• Price trend: Prices have softened 8.40% compared with last year.
• Clean inventory: 85.1% of listings are accident-free.

If you find a listing below $41,804, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2023 Audi S4's resale value?

The current average of $41,804 sits slightly below last year's $45,635.

That price movement suggests the S4 has already absorbed some depreciation, which can help you as a buyer today. For a future seller, it means resale value may continue to depend heavily on mileage, condition, and how well the car has been maintained. If you keep the car clean, documented, and accident-free, you should be in a stronger position when it is time to sell.

Should I buy a 2023 Audi S4 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:

• 34.2% of listings are priced as good or great deals.
• Accident-free inventory is solid at 85.1% — always verify the vehicle history report.

The bottom line: The 2023 Audi S4 is the right pick if you want a quick, all-wheel-drive luxury sedan with a polished cabin and a market that has become more buyer-friendly. If you are especially price-sensitive, you can also compare nearby model years to see whether a similar car offers a better deal, but the 2023 is a strong primary target when you want the balance of performance, usability, and value.
