Is the 2021 Audi A4 a good car?

Yes — the 4.75/5 user rating points to strong owner satisfaction. The 2021 Audi A4 stands out as a compact luxury sedan that blends strong technology, respectable efficiency, and a well-rounded driving character. It also offers a premium feel without stepping into something larger or more expensive, which makes it appealing if you want a used luxury sedan that still feels modern. Its standard equipment is generous for the class, and the available all-wheel drive adds appeal if you want extra traction in poor weather.

32.9% of listings are priced as good or great deals, which gives you some room to shop selectively.

Is the 2021 Audi A4 reliable?

Owners rate it 4.75/5, a strong signal of long-term satisfaction. The 2021 Audi A4’s appeal comes from its balanced character, strong technology, and premium everyday usability. It also benefits from a modern-feeling cabin and a well-equipped base trim, which can make it feel like a smart used-car value relative to newer competition.

For used buyers, the main long-term ownership risk is that a premium sedan’s upkeep can become more demanding if condition and maintenance history are not carefully checked.

What should I look for when buying a used 2021 Audi A4?

Accident-free inventory is solid at 76.1% — always verify the vehicle history report.

You should prioritize a history report first, then focus on a pre-purchase inspection so you can confirm the car’s condition matches the listing. Pay close attention to signs of wear in the cabin, electronics, and drivetrain behavior, since those areas matter most in a used luxury sedan. If you can, compare multiple examples so you can separate a clean, well-kept car from one that only looks good online.

What is the 2021 Audi A4's resale value?

The current average of $22,074 sits slightly below last year's $23,851.

That softer pricing can help you buy at a more favorable point in the cycle, but it also means future resale gains may be limited if the market stays soft. If you plan to sell later, a well-kept example with strong equipment and clean history should be easier to move than one with visible wear or a questionable record. The A4’s premium badge and broad appeal help support demand, especially when the car presents well.

Vehicles with strong owner satisfaction ratings, like this model year's 4.75/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2021 Audi A4 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 32.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 76.1% — always verify the vehicle history report.
• Price trend: Prices have softened 7.45% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.

Consider the 2022 if:

• At $24,129, the 2022 costs more than the current year's $22,074 average.
• It feels fresher and more modern.

The bottom line: You should start with the 2021 if you want the better value and a broader chance of finding a deal. If you’re willing to pay more for a newer-feeling alternative, the 2022 is the better secondary path. For price-sensitive buyers, the 2021 is the smarter place to focus first.
