Well, that's us had our C7 2.0 tdi Avant Black for a bit now - long enough to do a proper comparison and thought I'd come on for a bit of a moan.

My wife runs the new A6 and I've still got a C6 2.7 tdi SE and after having driven the new one for a week while we've been away down in Wales I definitely much prefer my C6. The build quality of the older cars just seems superior. We've had Audis for a good few years now and have had the privilege of owning A4, A6 and Q7 models and I've got to say, I'm most disappointed with the new A6.

It shudders pulling away in 1st gear. My C6 also does this but that's to be expected from a 123000 mile car on its first clutch / DMF - not a brand new car with only 13000 miles on it.

The interior feels a bit cheap and the cars been back to the dealer already to have the hazard light switch re fitted after it partially disappeared into the dash.

The exterior trim has also come loose at the drivers side quarter glass.

MMI system always freezes when bluetoothed to iPhone 6 and playing music.

On the whole pretty disappointed. Never had any real trouble with our previous cars. The wife originally fancied an A7 after this one but I think were both reconsidering after this car.
