Had the A6 BiTDi for just over 6 years. Apart from the new Turbo and a few minor things to fix, it's been a joy. I have been umming and arring about changing it but as it's completely paid off and I've only put about 40K miles on it I just can't justify taking on finance for something better (looking at you M5). It had a little tune at Audi Doctor in Stockport at the end of the year and it's now finally getting the calipers painted whilst alloys are SMART repaired. (I should really rip last years NT sticker off of the windscreen)
