What should I look for when buying a used 2018 Audi A5 Sportback?

At 61.5% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a thorough inspection of bodywork, panel alignment, and signs of prior repair. Because this model is positioned as a premium hatchback with a strong feature set, you’ll also want to confirm that the equipment you care about is actually present on the specific car you’re considering. Focus on condition first, then compare trim content so you don’t overpay for missing features.

Key things to evaluate:

• Trim level: Premium Plus adds blind-spot monitoring, rear cross-traffic alert, and Vehicle Exit Assist, while Prestige adds front and rear parking sensors, a top-view camera system, and more advanced Audi Connect and driver-assistance content. The base trim is the one most likely to leave you wanting more convenience and safety equipment.
• Powertrain: The A5 uses a turbocharged 2.0-liter four-cylinder with 252 horsepower and 273 pound-feet of torque, paired with a 7-speed dual-clutch transmission and standard Quattro all-wheel drive.
• Safety package: Every A5 Sportback includes forward-collision warning, low-to-moderate-speed automatic emergency braking, pre-impact preparation, and post-impact braking. Premium Plus adds blind-spot monitoring, rear cross-traffic alert, and Vehicle Exit Assist, while Prestige adds parking sensors, a top-view camera, adaptive cruise control, lane-departure warning, lane-keeping assist, automatic high beams, and traffic-sign recognition.
• Infotainment: Audi Virtual Cockpit uses a 12.3-inch digital display and is optional on Premium Plus and standard on Prestige. The MMI Touch system brings an 8.3-inch display and handwriting recognition, and the car also offers Audi Connect features plus a 4G LTE Wi-Fi hotspot on higher packages.
• Fuel efficiency: The expert review says the car returned 22.5 mpg on a test loop and notes an EPA rating of 27 mpg in combined driving.

Which 2018 Audi A5 Sportback trim should I buy?

The 2018 Audi A5 Sportback is offered in 3 trim levels: Premium, Premium Plus, Prestige.

Here's the short version:

• Premium: This is the entry point, and it gives you the core A5 Sportback experience with the standard safety and performance hardware. It makes sense if you want the style and utility first and can live without the extra convenience and driver-assistance features.
• Premium Plus: This is the best-value trim because it adds blind-spot monitoring, rear cross-traffic alert, Vehicle Exit Assist, and access to more tech content such as Audi Virtual Cockpit. It’s the trim that most clearly balances price and equipment.
• Prestige: This is the most fully equipped version, adding front and rear parking sensors, a top-view camera system, standard Audi Virtual Cockpit, a head-up display, and the most advanced driver-assistance package. Choose it if you want the most luxury and convenience content.

The safety-package upgrades are especially meaningful as you move up the lineup, with the most advanced driver-assistance features reserved for Prestige.

What is the 2018 Audi A5 Sportback's resale value?

The current average of $17,476 sits slightly below last year's $18,945.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable point in the cycle. For a future seller, that also means resale value will depend heavily on condition, mileage, and equipment because the broader market has shown some softness. Well-kept examples with desirable trim content should hold up better than cars with visible wear or missing features.

Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.
