Used 2021 Audi Q3 for Sale nearMilwaukee, WI

How much does the 2021 Audi Q3 cost?

Prices have softened 11.32% compared to this time last year, making it a favorable time to shop this model year.

There are 1,024 listings available, which gives you a solid pool of options to compare.

Is the 2021 Audi Q3 a good car?

Yes — the 2021 Audi Q3 earns a 4.75/5 user rating and an 8.17/10 expert rating. The model scores 9/10 across Form and function and Safety.

You get a subcompact luxury SUV that emphasizes a refined ride, useful technology, and standard driver assistance features. It also brings engaging road manners and plenty of passenger space for the class, which makes it easy to live with if you want a small luxury SUV that feels polished on the road.

The trade-offs are real, though: the interior materials can feel cheap, the back seat is cramped, and cargo space is limited. It is also described as poor value for money, so you should weigh the tech and ride quality against those practical compromises.

Only 36.9% of listings are priced as good or great deals, so the market is selective rather than especially bargain-heavy.

Is the 2021 Audi Q3 reliable?

Owners rate it 4.75/5, a strong signal of long-term satisfaction.

The Q3’s refined ride and standard driver assistance features support the impression of a well-sorted luxury SUV, and the expert writeup also points to helpful in-car tech and a comfortable, easygoing driving experience. Its turbocharged powertrain is described as lively in stronger tune, with solid passing power and a comfortable overall balance.

The cost side is also reassuring: the Q3 can run on regular gasoline, which helps keep day-to-day ownership simpler than many luxury rivals. For used buyers, the main long-term risk is that its premium positioning can still bring higher repair and upkeep costs than a mainstream SUV, so condition and service history matter.

What should I look for when buying a used 2021 Audi Q3?

Accident-free inventory is solid at 78.8% — always verify the vehicle history report.

You should still check the report carefully, because a clean listing percentage does not replace a proper history review. Prioritize a pre-purchase inspection that focuses on interior wear, rear-seat usability, and cargo-area condition, since those are the areas where the Q3’s compromises are most likely to show up. It is also worth confirming that the technology and driver-assistance features work as expected.

Key things to evaluate:

• Trim level: The Premium trim includes leather upholstery, 12-way power-adjustable front seats, heated front seats, dual-zone climate control, a panoramic sunroof, an 8.8-inch touchscreen infotainment system, a power liftgate, four USB ports, and several driver assistance features. The Premium Plus adds remote start, pushbutton start, remote keyless entry, wireless device charging, and a hands-free power liftgate. The Premium Plus is the best-value trim if you want more convenience features without moving into option-package territory.
• Powertrain: The Q3 uses a turbocharged 2.0-liter four-cylinder engine with 184 horsepower and 221 pound-feet of torque, paired with an eight-speed automatic transmission and Quattro all-wheel drive. The S-Line version raises output to 228 hp and 258 lb-ft, and the stronger setup is described as a great fit because it feels lively and improves passing power.
• Safety package: Audi Pre Sense and Pre Sense Front are standard, and Pre Sense Front includes forward-collision warning, automatic emergency braking, and pedestrian detection. Lane-departure warning is standard as well. Optional features include blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, traffic-sign recognition, a 360-degree camera system, front-and-rear parking sensors, and self-parking assist.
• Infotainment: The standard setup is an 8.8-inch touchscreen with Audi MMI, Android Auto, and wireless Apple CarPlay. The upgraded system is a 10.1-inch touchscreen with navigation. Wireless device charging, satellite radio, and a Bang & Olufsen 15-speaker premium audio system are also available.
• Fuel efficiency: The Q3 Quattro is rated at 22 mpg city, 30 mpg highway, and 25 mpg combined. The S-Line Quattro returns 20 mpg city, 28 mpg highway, and 23 mpg combined.

Which 2021 Audi Q3 trim should I buy?

The 2021 Audi Q3 is offered in 2 trim levels: Premium and Premium Plus.

Here's the short version:

• Premium: This is the entry point, but it still gives you leather upholstery, heated front seats, a panoramic sunroof, the 8.8-inch touchscreen, and standard driver assistance features. If you want the lowest starting price and can live without the extra convenience features, this is the trim to start with.
• Premium Plus: This is the trim to target if you want the best balance of equipment and value. It adds remote start, pushbutton start, remote keyless entry, wireless device charging, and a hands-free power liftgate, making it the smarter pick for most shoppers.

For added safety equipment, look for the available Convenience Package and other driver-assistance options if you want features beyond the standard suite.

Is now a good time to buy a used 2021 Audi Q3?

This is a moderate market for selective buyers, so it rewards comparison shopping more than impulse buying.

• Deal availability: 36.9% of listings are priced as good or great deals.
• Inventory: There are 1,024 listings available.
• Price trend: Prices have softened 11.32% compared with last year.
• Clean inventory: 78.8% of listings are accident-free.

If you find a listing below $21,160, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Audi Q3's resale value?

The current average of $21,160 sits slightly below last year's $23,862.

That decline suggests the Q3 has become more affordable for used buyers, but it also means a future seller may face a softer pricing environment than before. If you buy well and keep the vehicle in strong condition, you can help protect value, but the market is still signaling that this model year is not commanding the same prices it did a year ago.

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.

Is the 2021 Audi Q3 safe?

The 2021 Audi Q3 comes standard with Audi Pre Sense and Pre Sense Front, which includes forward-collision warning, automatic emergency braking, and pedestrian detection. Lane-departure warning is standard as well, and optional safety tech includes blind-spot monitoring, rear cross-traffic alert, adaptive cruise control, traffic-sign recognition, a 360-degree camera system, front-and-rear parking sensors, and self-parking assist.

It earns a 9/10 safety score from our experts.

The 2021 update also added additional high-tech safety features, which strengthens the Q3’s appeal if you want a small luxury SUV with a broad standard safety base. If you want the fullest driver-assistance setup, you should look closely at the available option packages, since some of the more advanced features are not standard on every trim.

Should I buy a 2021 Audi Q3 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:

• 36.9% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.8% — always verify the vehicle history report.
• Price trend: Prices have softened 11.32% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• The 2021 model gains additional high-tech safety features, and the top-tier Prestige trim’s equipment is now available through option packages.

The bottom line: The 2021 Audi Q3 makes the most sense if you want a refined small luxury SUV with strong tech, standard safety features, and a lower used price than it had a year ago. If you are especially price-sensitive, this year is attractive because the market has softened and there are still plenty of listings to compare, but you should be selective about condition and equipment because the Q3’s value proposition is not its strongest trait.
