Used 2021 Audi Q3 for Sale nearPhiladelphia, PA

How much does the 2021 Audi Q3 cost?

Prices have softened 11.24% compared to this time last year, making it a favorable time to shop this model year.

There are 994 listings available, which gives you a meaningful pool to compare prices and equipment.

Is the 2021 Audi Q3 a good car?

Yes — with a 4.75/5 user rating and an 8.17/10 expert rating, the 2021 Audi Q3 lands in strong territory for shoppers who want a subcompact luxury SUV that feels polished and easy to live with. It stands out for its refined ride, useful technology, and standard driver assistance features, and it also brings plenty of passenger space for the class.

The model scores 9/10 across Form and function and Safety.

The trade-offs are real, though: the interior materials can feel cheap, the back seat is cramped, and cargo space is limited. If you want a small luxury SUV that prioritizes road manners and tech over maximum practicality, the Q3 fits that brief well.

36.5% of listings are priced as good or great deals, which suggests there are still some attractive opportunities if you shop carefully.

Is the 2021 Audi Q3 reliable?

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

The Q3’s appeal comes from its refined ride, standard all-wheel drive, and helpful technology, all of which support an ownership experience that feels composed and easy to live with. Its turbocharged setup is described as lively in stronger form, while the cabin and controls are designed to feel modern and straightforward.

The Q3 can run on regular gasoline, which helps keep day-to-day operating costs more manageable than some luxury rivals. For used buyers, the main long-term risk is that its premium positioning does not fully erase the practical compromises in space and materials.

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

Accident-free inventory is solid at 78.6% — always verify the vehicle history report.

You should still check the history report carefully and prioritize a pre-purchase inspection, especially if you are considering a higher-mileage example or one with optional equipment. Focus on cabin condition, since the interior materials are a known weak point, and make sure the tech 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 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 Technology Package adds a larger touchscreen, a premium stereo, and a digital instrument panel.
• 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 is tuned to 228 hp and 258 lb-ft, and it feels livelier with stronger 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. 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 check whether the example you are considering has the features you want.
• Infotainment: The standard system uses an 8.8-inch touchscreen with Audi MMI, standard Android Auto, and wireless Apple CarPlay. The upgraded system is a 10.1-inch touchscreen with navigation, and available tech includes wireless device charging, satellite radio, and a Bang & Olufsen 15-speaker premium audio system.
• Fuel efficiency: The Quattro model 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 value play if you want the core Q3 experience without stretching for extras. You still get leather upholstery, heated front seats, dual-zone climate control, a panoramic sunroof, the 8.8-inch touchscreen, a power liftgate, four USB ports, and standard driver assistance features, so it covers the essentials well.
• Premium Plus: Choose this if you want a more complete luxury feel. It adds remote start, pushbutton start, remote keyless entry, wireless device charging, and a hands-free power liftgate, making it the better fit if convenience features matter most to you.

The safety package is strong across the lineup, with Audi Pre Sense and Pre Sense Front standard, while additional driver-assistance features remain available depending on the trim and package.

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

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you are patient and compare listings carefully.

• Deal availability: 36.5% of listings are priced as good or great deals.
• Inventory: There are 994 listings available.
• Price trend: Prices have softened 11.24% compared with last year.
• Clean inventory: 78.6% of listings are accident-free.

If you find a listing below $21,213, 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 $21,213 sits slightly below last year's $23,899.

That decline suggests the Q3 has become more affordable for used buyers, but it also means a future seller may need to price competitively to stand out. The current market still shows meaningful inventory and a decent share of good or great deals, so buyers have options and sellers may face some pressure on pricing.

Even so, the Q3’s strong equipment list and premium-brand appeal can help support demand when the vehicle is well kept and properly equipped. If you maintain it carefully and keep the history clean, you should be in a better position when it is time to sell.

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.
