My Audi A6 hasn't let me down. I use it daily with work, its easy to drive, esp as I am usually loaded down - I definitely take advantage of the large boot. The Satnav is really good, esp as I travel long distance day to day. It is economical too. It is larger than my old A6, which is slightly trickier to park, but no problem. Would buy again.
Good big car for travelling.
Nothing major - was expensive to buy, although I do get my use out of it.
