B6 A4 to A6?

[Rocko]

Having gone as far as I can with my A4 Im thinking about changing up to an A6 1.9TDi and starting all over again with the modifying process.

Is there much difference between the two?

Depends on the age of A6?

The latest model willbe an improvement of course, a similar age model wont be a big difference, especially if they are the same engine size.
