With 4 used Audi A6 models currently available on Motoring Today, ranging in year from 2016 to 2022, understanding the real cost of ownership is essential before making a purchase. The cheapest cash price for an Audi A6 starts from £13,992, with representative monthly finance examples available from £322. These figures offer a starting point, but the true cost extends beyond the initial purchase price. Running a used Audi A6 involves several ongoing expenses. Fuel or energy costs will be a regular consideration, depending on whether you opt for a petrol, diesel, or hybrid variant, and how you use the car. Insurance premiums vary significantly based on factors like your age, driving history, and where you live. Road tax, or Vehicle Excise Duty (VED), is another annual cost, influenced by the car's age and emissions. Regular servicing is crucial for maintaining your A6's reliability and ensuring its longevity, with costs depending on the service schedule and any necessary repairs. Finally, depreciation, while not a direct out-of-pocket expense, represents the car's loss in value over time and is a significant factor in overall ownership cost. Detailed calculators and further information on these aspects are available on this page, and remember that finance is subject to status.
