The Audi A6 will likely be considered alongside other big German premium machines, such as the Mercedes-Benz E-Class and the BMW 5 Series, as well as other rivals like the Jaguar XF and Volvo S90. A look at the purchase prices suggests very little between them, with the Jaguar being slightly cheaper and the Audi sitting towards the top of a very small range. Delve into the running costs and again, there’s very little difference. The Jag, BMW and Audi all look to cost virtually the same over several years when you factor in fuel economy, resale values and servicing, the Merc and Volvo slightly more, but not by much. Ultimately this is a decision based on which car you like the best, rather than the lure of financial savings.
