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

At 64.2% 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 in a premium hatchback: interior wear, electronics, and whether the car still feels as refined as it should on the road.

Key things to evaluate:

• Trim level: The car is offered in A5 and S5 model series, with Premium, Premium Plus, and Prestige trim levels. The Premium Plus trim adds features such as Audi Virtual Cockpit, while Prestige brings more upscale equipment like a head-up display and additional convenience tech.
• Powertrain: The A5 uses a turbocharged 2.0-liter 4-cylinder engine, while the S5 uses a turbocharged 3.0-liter V6 engine. The A5 is paired with a 7-speed dual-clutch automated manual transmission and standard Quattro all-wheel drive.
• Safety package: Every A5 Sportback includes forward-collision warning, low-to-moderate-speed automatic emergency braking, occupant-prep technology, 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 system, and the Driver Assistance Package.
• Infotainment: Audi Virtual Cockpit uses a 12.3-inch digital instrumentation screen and is optional on Premium Plus and standard on Prestige. The MMI Touch infotainment system brings an 8.3-inch display and handwriting recognition, and Audi Connect features expand with higher trims.
• Fuel efficiency: The car returned 22.5 mpg on the expert test loop, compared with 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 powertrain, Quattro all-wheel drive, and the car’s style-and-utility formula. It makes sense if you want the lowest-cost way into the model and are comfortable skipping some of the richer tech and convenience upgrades.
• Premium Plus: This is the best-value trim for most shoppers because it adds Audi Virtual Cockpit and important safety and convenience upgrades, including blind-spot monitoring, rear cross-traffic alert, and Vehicle Exit Assist. If you want the strongest balance of features and price, 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, and the Driver Assistance Package. It suits you best if you want the most advanced tech and driver-assistance content available on this model.

Safety-wise, the Premium Plus trim is the key step up because it adds blind-spot monitoring, rear cross-traffic alert, and Vehicle Exit Assist.

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

This is a moderate, selective buyer’s market, so you have room to shop, compare, and wait for the right listing.

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

The current average of $17,886 sits slightly below last year's $19,834.

That decline suggests the market has already adjusted downward, which can help you as a buyer today but may also mean future resale gains are limited unless the car is especially well kept. If you plan to sell later, condition and equipment will matter a lot, because shoppers in this segment tend to pay more for cars that feel premium and are loaded with desirable features.

Vehicles with strong owner satisfaction ratings, like this model year's 4.86/5, tend to retain buyer demand, which supports resale value over time.

Is the 2018 Audi A5 Sportback safe?

The 2018 Audi A5 Sportback earns five-star ratings overall from NHTSA, though frontal-impact protection for the driver and front-seat passenger measures four-star.

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

Every A5 Sportback includes forward-collision warning, low-to-moderate-speed automatic emergency braking, occupant-preparation technology, and post-impact braking. 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 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 that the federal crash results show a weaker frontal-impact result than the overall score, so if safety is a top priority, you should pay close attention to trim level and condition.

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

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 35.8% of listings are priced as good or great deals.
• At 64.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 9.82% compared with last year.
• Owners rate it 4.86/5 — a strong satisfaction signal.
• The 2018 Audi A5 Sportback stands out by blending style, performance, and utility in a five-door hatchback body.

The bottom line: If you want the strongest mix of style, utility, and value in this model year, the 2018 is the one to focus on, especially if you can find a clean, well-equipped example in Premium Plus or Prestige trim. If you’re more price-sensitive, keep shopping the market closely and prioritize the best-maintained car you can find rather than stretching for a higher-mileage example with more wear.
