We just purchased the 2010 Audi TDI S- Line with the Prestige Pkg. It was one of the first to land here in the US. For reference, we traded in our 2006 Mercedes ML 500 - which we loved, but had many problems. First of all, the Diesel is absolutely great. It has the pickup of a V8 with the fuel economy of a V4. With 14 miles on the car, I drove it from Houston to Dallas. I averaged 28.9 MPG. The gauge barely moved off off 'F'. It is very roomy, drives extremely smooth, is very quiet and has conveniences that not only make it safer (i.e., side assist), but more enjoyable to drive. Also, the 3rd gen MMI is very easy to use and practical.
