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. 34.9% of listings are priced as good or great deals, which suggests there are still some attractive opportunities if you shop carefully.

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 a well-equipped interior. It also benefits from standard all-wheel drive and a smooth ride, which can make ownership feel reassuring in daily use.

For long-term ownership, you should still expect a used Audi to demand more maintenance attention than some 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 84.4% — always verify the vehicle history report.

You should prioritize a history report first, then inspect the car closely for signs of prior damage, uneven wear, or deferred maintenance. Focus on overall condition, because a well-kept example is more likely to deliver the polished ownership experience this model is known for.

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

This looks like a moderate, selective buyer's market, so you can afford to compare listings and wait for the right one.

• Deal availability: 34.9% of listings are priced as good or great deals.
• Inventory: There are 109 listings available.
• Price trend: Prices have softened 8.17% compared with last year.
• Clean inventory: 84.4% of listings are accident-free.

If you find a listing below $42,092, 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 $42,092 sits slightly below last year's $45,837.

That price movement suggests the market has already absorbed some depreciation, which can help you as a buyer today. If you plan to sell later, the softer pricing means your future resale value will depend heavily on mileage, condition, and maintenance history. A clean, well-documented example should hold up better than one with visible wear or incomplete records.

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:

• 34.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 84.4% — always verify the vehicle history report.
• Price trend: Prices have softened 8.17% compared with last year.

The bottom line: The 2023 is a strong choice if you want the S4’s balance of speed, standard all-wheel drive, and everyday usability without paying for a newer model year. If you are more price-sensitive, you can also use the softer market to compare nearby years and focus on the cleanest, best-priced example rather than chasing a specific badge year.
