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

At 62.1% 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 pre-purchase inspection, especially if the car has had bodywork or shows signs of uneven wear. Focus on condition details that matter most in a premium hatchback: panel alignment, interior wear, electronics, and whether the car’s equipment matches the trim level advertised. If you’re comparing multiple listings, the best value usually comes from the cleanest example with the most complete service history.

Key things to evaluate:

• Trim level: Premium Plus is the most compelling value because it adds Audi Virtual Cockpit, blind-spot monitoring with rear cross-traffic alert, and Vehicle Exit Assist, while Prestige brings the most equipment with a head-up display, front and rear parking sensors, a top-view camera system, and the Driver Assistance Package. The base trim is lighter on convenience and driver-assistance features.
• Powertrain: The A5 uses a turbocharged 2.0-liter four-cylinder engine with 252 horsepower and 273 pound-feet of torque, paired with a 7-speed dual-clutch automated manual transmission and standard Quattro all-wheel drive. Audi says 60 mph arrives in 5.7 seconds.
• 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 with rear cross-traffic alert and Vehicle Exit Assist, while Prestige adds front and rear parking sensors, a top-view camera system, and the Driver Assistance Package with 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 adds an 8.3-inch display and handwriting recognition, and Audi Connect packages expand connected services.
• Fuel efficiency: The car returned 22.5 mpg on the test loop, below its 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 powertrain, Quattro all-wheel drive, and the car’s strong style and utility. It makes sense if you want the lowest-cost way into the model and are comfortable giving up some convenience and driver-assistance upgrades.
• Premium Plus: This is the best-value trim because it adds Audi Virtual Cockpit, blind-spot monitoring with rear cross-traffic alert, and Vehicle Exit Assist, while also unlocking more tech and convenience options. If you want the sweet spot between price and equipment, this is the trim to target.
• Prestige: This is the most fully equipped version, adding a head-up display, front and rear parking sensors, a top-view camera system, standard Audi Virtual Cockpit, standard Bang & Olufsen audio, and the Driver Assistance Package. Choose this if you want the most advanced tech and the fullest safety and convenience content.

Prestige also gets the exclusive Driver Assistance Package, while some of its connected and safety features are optional or unavailable on lower trims.

Is now a good time to buy a used 2018 Audi A5 Sportback?

The market looks moderately favorable if you’re a selective buyer.

• Deal availability: 35.1% of listings are priced as good or great deals.
• Inventory: There are 282 listings available.
• Price trend: Prices have softened 7.49% compared with last year.
• Clean inventory: 62.1% of listings are accident-free.

If you find a listing below $17,626, that's toward the low end of the year-round range and worth acting on quickly.

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

The current average of $17,662 sits slightly below last year's $19,091.

That price movement suggests the model has already absorbed a meaningful amount of depreciation, which can help future resale stability if you buy at the right price. For a seller, the key is to avoid overpaying now, because your eventual resale outcome will depend heavily on how much value is left to preserve. A clean history, strong equipment, and desirable trim content should help support demand when it’s time to sell.

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.

Is the 2018 Audi A5 Sportback safe?

The 2018 Audi A5 Sportback earns an overall score of five stars from NHTSA, but frontal-impact protection for the driver and front-seat passenger measures four stars.

It earns an 8/10 safety score from our experts.

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 with rear cross-traffic alert and Vehicle Exit Assist, while Prestige adds front and rear parking sensors, a top-view camera system, and the Driver Assistance Package with adaptive cruise control, lane-departure warning, lane-keeping assist, automatic high beams, and traffic-sign recognition. The main caveat is the lower frontal-impact result, so shoppers who prioritize crash performance should pay close attention to that detail.

Should I buy a 2018 Audi A5 Sportback or consider a different year?
