My current A4 has sports seats with Alcantara, which I love, but sadly the comparable (Dinamica) seats that are available in other markets are not an option in the US. We just have the standard leather seats, or the S-line sports seats, which are also leather. They are only available as part of the S-line package, but I'm not particularly interested in the other aspects of the S-line package. So I'm trying to weigh the value of the sports seats. I assume the standard seats don't have the extendable thigh support that the sports seats have, but that's not an issue - I don't have long legs, and keep them fully retracted in my current car. Clearly the sports seats have more aggressive side bolsters, though I'm not sure how beneficial that is in an SUV. Can anyone comment on any other differences? Difference in comfort? Difference in how much of the seating surfaces are leather vs. leatherette?
