At 65.3% 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 higher mileage or visible cosmetic wear. Focus on how the cabin, electronics, and drivetrain feel in real use, since the A5 Sportback’s appeal depends heavily on its blend of refinement, tech, and driving enjoyment.

The performance tuning is strong, but the review notes a small delay in off-the-line response.
• Safety package: Standard safety equipment includes forward-collision warning, low-to-moderate-speed automatic emergency braking, impact-preparation 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 with adaptive cruise control, lane-departure warning, lane-keeping assist, automatic high beams, and traffic-sign recognition.
