For Sale: 2013 Audi A3 Cabriolet S Line Final Edition - High Spec, 30 Road Tax, 50+ MPG We're selling our much-loved Audi A3 Cabriolet S Line Final Edition - a stylish and economical convertible with plenty of spec. It has the reliable 2.0 TDI engine, but the tax is just 30 a year. When driven sensibly, it easily returns over 50 MPG. We've owned the car for the last 3.5 years, covering around 24,000 miles in that time. It's been a great little vehicle, but sadly we no longer have enough parking space to keep it. The car is in very good condition overall, but naturally shows some age-related marks on the bodywork and alloy wheels, as you'd expect for its year. There are plenty of receipts for all services and repairs. Front tyres are brand new. If you're looking for a well-specced, reliable, and fun convertible that's cheap to run - this is a great option.
