Used 2021 Audi Q3 for Sale nearPhiladelphia, PA

How much does the 2021 Audi Q3 cost?

Prices have softened 11.75% compared to this time last year, making it a favorable time to shop this model year.

There are 1,074 listings available, which suggests solid inventory for you to compare prices and equipment.

Is the 2021 Audi Q3 a good car?

Yes — the 2021 Audi Q3 earns a 4.8/5 user rating and an 8.2/10 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 stands out for its impressive technology, impressive stereo, and great ride quality.

The trade-offs are clear: the cabin materials can feel cheap, the back seat is cramped, and cargo space is limited. That means the Q3 makes the most sense if you value comfort, tech, and a polished driving feel more than maximum utility.

The share of good and great deals sits at 38.7%, which gives you some room to shop selectively.

Is the 2021 Audi Q3 reliable?

Owners rate it 4.8/5, a strong signal of long-term satisfaction.

The Q3’s standard equipment and refined driving character support the case for dependable everyday use, especially if you want a small luxury SUV that feels well equipped from the start. Its turbocharged four-cylinder setup is described as lively, and the ride and handling balance is a strength rather than a compromise.

It also runs on regular gasoline, which helps keep day-to-day ownership simpler and less costly than some luxury rivals. For used buyers, the main long-term risk is that the Q3’s premium feel does not erase its tighter cabin and limited cargo room, so condition and maintenance history matter a lot.

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

Accident-free inventory is solid at 80.4% — always verify the vehicle history report.

You should still check the vehicle history report carefully and prioritize a pre-purchase inspection, especially if you’re shopping outside the cleanest listings. Focus on interior condition, because the cabin materials are a known weak point, and make sure the back seat and cargo area fit your needs before you commit.

Key things to evaluate:

• Trim level: The Premium trim gives you 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 high-tech 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 better value if you want more convenience features without stepping into options packages.
• Powertrain: The standard turbocharged 2.0-liter four-cylinder makes 184 horsepower and 221 pound-feet of torque, paired with an eight-speed automatic transmission and Quattro all-wheel drive. The S-Line version uses the same engine tuned to 228 hp and 258 lb-ft, and it is described as the better fit because it feels livelier and stronger for passing.
• 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 too. 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 are available, so base-trim shoppers should confirm which extras are included.
• Infotainment: The standard setup is an 8.8-inch touchscreen with Audi MMI, standard Android Auto, and wireless Apple CarPlay. A 10.1-inch touchscreen with navigation is available, along with wireless device charging, satellite radio, and a Bang & Olufsen 15-speaker premium audio system. Audi Virtual Cockpit is 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. It makes sense if you want the lowest starting price and are comfortable skipping some convenience upgrades.
• Premium Plus: This is the best-value trim because it adds remote start, pushbutton start, remote keyless entry, wireless device charging, and a hands-free power liftgate. If you want the Q3 to feel more complete in daily use, this is the trim to target.

The safety package includes Audi Pre Sense and Pre Sense Front, with additional driver-assistance features available through options packages.

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

This is a moderate market for selective buyers, so you can shop patiently but still move quickly on the right listing.

• Deal availability: 38.7% of listings are priced as good or great deals.
• Inventory: There are 1,074 listings available.
• Price trend: Prices have softened 11.75% compared with last year.
• Clean inventory: 80.4% of listings are accident-free.

If you find a listing below $20,534, 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 $20,534 sits slightly below last year's $23,269.

That decline suggests the market has become more favorable for buyers, but it also means future sellers may face some pressure if prices continue to soften. If you buy now, you’re entering at a lower baseline than a year ago, which can help limit depreciation exposure compared with a stronger pricing environment.

The Q3’s appeal should still support demand among shoppers who want a small luxury SUV with standard tech and a refined ride. Vehicles with strong owner satisfaction ratings, like this model year's 4.8/5, 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 additional driver-assistance features such as 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 are available.

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

That standard safety setup is a strong point for the Q3, especially if you want a small luxury SUV that comes well equipped without needing to jump immediately into higher trims. The main caveat is that some of the more advanced features are optional, so you should confirm exactly which driver-assistance items are included on the used example you’re considering.

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:

• 38.7% of listings are priced as good or great deals.
• Accident-free inventory is solid at 80.4% — always verify the vehicle history report.
• Price trend: Prices have softened 11.75% compared with last year.
• Owners rate it 4.8/5 — a strong satisfaction signal.
• The 2021 model gains additional high-tech safety features and loses the top-tier Prestige trim, with those features now available through options packages.

The bottom line: The 2021 is a smart pick if you want the Q3’s refined ride, standard safety tech, and strong everyday usability at a softer used-car price. If you’re especially price-sensitive, you can shop carefully for a clean, well-equipped example and focus on the Premium Plus trim for the best balance of features and value.
