I did try searching to see if the question was ever posted before, but found nothing. I will be in the market soon to update/upgrade from my B6 USP and leaning on the larger platform of the C7 due to the great reputation of the 3.0 and Auto trans over the B8S4 with it's DSG. My question is: What are, or are there differences in options (functional or aesthetic),running gear,etc between the C7A6 and the C7A7 beyond the obvious rear seats,hatch and appearance? Does the A7 possess any higher quality interior bits or tech than the A6?
