Buying the 2018 Audi S6

A buyer's checks
Owners filed 4 complaints with NHTSA, most often about steering, electrical system and service brakes; have those parts checked. Check whether every recall was done, by the VIN, before you pay. Look at the tires, brakes and battery; they are costly to replace. NHTSA lists 1 recall campaigns for this model; ask the seller for proof each one was fixed.
The figures, translated
Its 4.0L 8-cylinder turbo drives through a 7-speed automatic. It calls for premium gas, which costs more a litre than regular. With all-wheel drive, it pulls away more surely on slippery roads, though it does not stop any shorter.
Expect about 38 litres for every 300 km, going by its 12.8 L/100 km combined rating. A 300 km weekend costs about $67.20 in energy at our price setting. The EPA estimates US$4,550 a year in fuel for 15,000 miles.
Who rents the S6
It suits someone whose own car is in the shop for a while. It suits people curious about the model who want to drive it before they buy.
Space, size and seats
Being a mid-size car, it is easy to park and comfortable on longer drives. In plain terms, its 453 litres of luggage space hold a family's bags for a long weekend.
Drive it on your own roads
Rent first, buy later: a week with the S6 answers the big questions. Rent it, live with it for a week, and decide with real experience. Renting first costs a fraction of the price of buying the wrong car.
Which one to look for
If you are unsure between two options, rent one of them for a week first. Look at a few listings of the same year and trim to get a feel for fair prices. If two trims share a powertrain, the difference is equipment, which you can check in person.
What it costs to run
Premium gas adds to the running cost compared with a car on regular. Get an insurance quote for this exact model before you buy; rates differ a lot between models. A 1,000 km month costs roughly $224 at our price setting.
