Audi A3 - Well-Maintained, Reliable, and Ready to Drive This Audi A3 has been looked after, with servicing carried out every 10,000 miles exactly as recommended by Audi's onboard notifications. It has been a brilliant, dependable car. The exterior is in great shape overall, with a few minor stone chips and a small thumb-sized dent. Inside it hasn't any issues. Only selling because I have moved to an Electric car.
