Used Audi A6

Although not market leading (it directly competes with two other German behemoths of car manufacturing), the A6 is a head turning choice in a class full of head turners. Bearing the Audi proviso for impeccable interiors, the A6 comes equipped with technology both incredibly sophisticated yet simple to use (Audi MMI, sat nav and a number of optional driver assist functions), while cabin size nears that of the class above it. The 2.0 TDi engine satisfies the need for power and efficiency, but for the more speed obsessed the performance of the 3.0 BiTDi V6 (0-62mph in 5.1 seconds), may prove more alluring.
