Used 2021 Audi Q3 for Sale nearAnaheim, CA

How much does the 2021 Audi Q3 cost?

Prices have softened 11.80% compared to this time last year, making it a favorable time to shop this model year.

There are 1,063 listings available, which gives you a decent amount of inventory 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.

It stands out as a subcompact luxury SUV that blends an engaging driving experience with useful technology and plenty of space for passengers. It also delivers a refined ride and standard driver assistance features, which helps it feel comfortable and easy to live with in a crowded class.

The main trade-offs are that the interior materials can feel cheap and the back seat is cramped, so you’re balancing polished road manners and tech against some practical compromises. It is also described as poor value for money, so the appeal is strongest if you prioritize comfort, technology, and driving polish over maximum utility.

With 36.1% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2021 Audi Q3 reliable?

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

The Q3 is presented as a refined, easy-to-live-with small luxury SUV, and its standard driver assistance features add to that sense of everyday confidence. Its expert writeup also emphasizes a comfortable ride and helpful in-car tech, both of which support a low-stress ownership experience.

It runs on a turbocharged 2.0-liter four-cylinder engine, and the writeup notes that the more potent version feels lively with solid passing power, while the less powerful base engine shows more turbo lag. It also says the Q3 can run on regular gasoline, which helps keep day-to-day ownership costs more manageable.

For used buyers, the biggest long-term risk is that the Q3’s premium feel can be offset by its tighter rear seat and limited cargo space, so make sure the vehicle still fits your real-world needs.

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

Accident-free inventory is solid at 79.7% — always verify the vehicle history report.

You should still check the history report carefully and prioritize a pre-purchase inspection, especially if you’re considering a higher-mileage example or one with optional equipment. Focus on cabin condition, seat wear, and how well the tech and driver-assistance features work, since those are central to the Q3’s appeal.

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 without chasing the highest-priced setup.
• Powertrain: The Q3 comes with a turbocharged 2.0-liter four-cylinder engine paired with an eight-speed automatic transmission and Quattro all-wheel drive. The standard version makes 184 horsepower and 221 pound-feet of torque, while the S-Line tune raises output to 228 hp and 258 lb-ft. The stronger setup feels livelier, while the base engine shows more turbo lag.
• 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 system uses an 8.8-inch touchscreen with Audi MMI, standard Android Auto, and wireless Apple CarPlay. An available 10.1-inch touchscreen adds navigation, and the available Audi Virtual Cockpit replaces the conventional gauge cluster with a digital display.
• 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, dual-zone climate control, a panoramic sunroof, an 8.8-inch touchscreen, a power liftgate, four USB ports, and standard driver assistance features. If you want the lowest starting price and the core Q3 experience, this is the trim to start with.
• Premium Plus: This trim adds remote start, pushbutton start, remote keyless entry, wireless device charging, and a hands-free power liftgate. It is the better choice if you want the Q3 to feel more complete in daily use, and it is the best-value trim for most shoppers.

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

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

This looks like a moderate market for selective buyers, so it makes sense to shop carefully and compare listings.

• Deal availability: 36.1% of listings are priced as good or great deals.
• Inventory: There are 1,063 listings available.
• Price trend: Prices have softened 11.80% compared with last year.
• Clean inventory: 79.7% of listings are accident-free.

If you find a listing below $21,023, 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 $21,023 sits slightly below last year's $23,837.

That decline suggests the market has already adjusted downward, which can help you as a buyer today but may limit upside if you plan to resell soon. If you buy at the right price, you reduce the chance of taking a steep depreciation hit in the near term.

The Q3’s broad appeal comes from its refined ride, useful technology, and standard driver assistance features, all of which help keep it attractive to future shoppers. 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 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.

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

The Q3’s safety setup is strong for the class, especially because key driver-assistance features are standard rather than reserved for higher trims. If you want more coverage, you’ll need to look for packages that add blind-spot monitoring, rear cross-traffic alert, and the more advanced parking and camera systems.

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:

• 36.1% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79.7% — always verify the vehicle history report.
• Price trend: Prices have softened 11.80% compared with last year.
• Owners rate it 4.75/5 — a strong satisfaction signal.
• For 2021, the Q3 gains additional high-tech safety features, and the features from its top-tier Prestige trim are now available as option packages.

The bottom line: The 2021 Q3 is the right pick if you want the updated safety content and the flexibility of package-based upgrades without moving to a newer model year. If you’re especially price-sensitive, a nearby year may still make sense, but the 2021 gives you a strong mix of tech, comfort, and standard safety equipment at a softened market price.
