Test-drove an A6 diesel alongside the equivalent 5-Series before deciding on a Citroen C6. I'm not sure why the Audi has so much praise for comfort when its ride/handling mix is so closely related to an Amish cart. It's unforgiving down potholed streets and tends to bounce occupants everywhere except recently resurfaced motorways. The new Mondeo feels far better, though the A4 due in 2008 supposedly has suspension improvements introduced on the RS4. Only then will I put my bottom back in an Audi!
