Used Audi A6 review: 2005-2009

The ride was blissfully smooth and supple on all surfaces.

The mid-sized prestige market has been a very lucrative one in the past 20 years or so, particularly for European carmakers like BMW and Mercedes-Benz, and more latterly Audi with its A6. Audi has been aggressively, and successfully, chasing market share and the A6 has been an important weapon in its campaign to overthrow its rivals.

The most obvious change to the A6 introduced in 2006 was the bold new grille, but that change alone said plenty about the model and the brand's intent. In one fell swoop the A6, and the brand, took on a more aggressive, in your face look. It emerged from the pack and said 'look at me'. If the grille was the centrepiece of the overhaul, there were other changes to the body as well. Again, given BMW's move to more sharply defined, chiselled lines, the smooth, sweeping lines of the Audi were appealing to the many buyers who found the BMW looks challenging.

The new A6 was larger than the previous model, with more cabin space and a larger boot, made even more useful thanks to a folding rear seat. The interior was nicely designed and finished, with comfortable and supportive seats, and everything else you could wish for in the segment. When first launched the A6 had a selection of engines ranging from a 2.4-litre V6 through to a 4.2-litre V8, along with a new 3.0-litre turbo diesel V6.

But in no time at all more engines were introduced, including a new fuel-efficient 2.0-litre TFSi unit. The transmission choices were a six-speed automatic with tiptronic shift control and a smooth CVT continuously variable automatic gearbox, and there was a choice of front-wheel drive or Audi's popular Quattro all-wheel drive system.

Not surprisingly given its price the A6 came with plenty of luxury features, like leather and wood trim, CD sound, power seats, sat-nav and a raft of others. On the road the A6 was a smooth operator aimed more at giving the executive a smooth ride than a driving thrill. It wasn't as sporty as a BMW 5-Series, but that was Audi's claimed point of difference. Even though it didn't pretend to be as sporty as its main rival it still displayed a fine handling balance with a reassuring neutral poise that dealt corners with a minimum of fuss. The ride, too, was blissfully smooth and supple on all surfaces, and bumps and broken pavement was soaked up with consummate ease.

IN THE SHOP

It's European, which means it comes with technology that can  sometimes be temperamental, and parts and repairs can be expensive. Before buying a second hand Audi it's a good idea to have it checked  by someone with experience in the brand, someone who can pick the faults and advise on what could go wrong. It's also well worthwhile to be on good terms with an independent Audi specialist who can not only expertly service your car, but also source more affordable parts if and when needed. Look for oil leaks around the engine and coolant leaks around the cooling system, check the service record, and inspect for poor crash repairs.
