What Car? says...
Many modern estate cars are so-called ‘lifestyle' models – which essentially means they have sleek looks and a posh badge, but are more suited to transporting terriers than wolfhounds. Not the Audi A6 Avant, though.
True, it is blessed with handsome looks and an upmarket badge, but, because it’s based on the A6 luxury saloon, it’s a big and genuinely practical choice. There are several petrol and diesel engines to choose from, the range kicking off with a couple of sensible four-cylinder engines and continuing via a couple of bigger V6s.
