I'm looking at buying a pre-reg A4. It's fitted with 19" alloys, leather interior and AMI. Now I'm changing from an A3 S0Line BE,because the ride is just too hard! (Must be getting old). Does an A4 ride any better and is a car with 19" going from the frying pan to the fire! The I-Pod interface in the A3 is a joke. How does the AMI compare? Does AMI give full track details in the colour screen. I only ask because there seem to be different specs of AMI available. This car has leather seats, which look nice. However, there is another car with B+O stereo, which appeals to me. Can't decide which is the better choice.
