Used Audi A4 Cars for Sale: Inspected, ULEZ Compliant & Ready to Buy

Why Buy a Used Audi A4?

The Audi A4 is a popular choice for drivers seeking a blend of comfort, performance, and efficiency. It’s a mid-sized executive car that suits both commuting and family life, with a reputation for solid build quality and a refined driving experience. Choosing a used Audi A4 means you can access premium features and German engineering at a much more accessible price, especially when buying through a transparent online auction like SecondCar.

Current Used Audi A4s for Sale

At the moment, you’ll find two 2017 Audi A4s available on SecondCar, covering both the saloon and estate (Avant) body types. These cars are petrol-powered, with one automatic and one manual, and current prices ranging from £1,300 to £1,700. Both have average mileages typical for their age and come with free downloadable inspection reports, so you know exactly what you’re bidding on. Every A4 here is ULEZ compliant, making them suitable for London and other Clean Air Zones.

Running Costs, Insurance & ULEZ

The 2017 Audi A4 offers reasonable running costs for its class. Expect real-world fuel economy of 40–50 mpg from the 1.4 and 2.0 TFSI petrol engines. Insurance is typically in groups 22–28, so premiums are moderate compared to more powerful executive cars. All current A4s in stock are ULEZ compliant, so you won’t pay extra charges in London or other Clean Air Zones. MOT and road tax costs are in line with other mid-sized saloons; always check the latest MOT history and advisories in the free report provided for each car.

What to Check When Buying an Audi A4 at Auction

• Review the full inspection report and condition grade
• Check the DVLA and MOT history for advisories or past failures
• Look for evidence of regular servicing (often shown in photos or notes)
• Confirm the car’s V5C logbook status and number of previous owners
• Read the HPI check for outstanding finance, write-off or theft markers
• Consider the running costs: fuel, insurance, tyres and typical repairs

SecondCar provides all these checks for free on every lot, so you’re never bidding blind. Each car’s page includes a gallery, downloadable report, and all the key data you need to make an informed decision.

How the Auction & Buy Now Process Works

Registering to buy is quick and free—just create an account with your email and mobile. Once verified, you can bid in timed online auctions or, for some cars, buy instantly at the Buy Now price. Bids increase in set increments (£100 for cars in this price range), and any last-minute bid extends the auction, so you have time to respond. If you win, you’ll receive an official invoice and can pay securely by bank transfer via Open Banking. Collection or UK delivery is available, and the V5C is transferred directly to you.

Why Buy Your Audi A4 on SecondCar?

SecondCar focuses on transparency and buyer protection. Every Audi A4 is independently inspected, with a clear report, DVLA/MOT data, and HPI-style finance and history checks. You’ll see exactly what you’re bidding on—no hidden issues or surprises. Our fee structure is simple: a 5% buyer’s premium (minimum £250), plus VAT on the fee only, with no VAT on the car price for margin-scheme vehicles. You pay securely by bank transfer, and can choose collection or delivery to your door. If you’re new to online car auctions, we have a full guide to walk you through the process.
