I'm about to change my 2007 Audi A6 Avant Quattro 3.0 TDI SE for the new model. As some roads are often poorly surfaced these days it has been suggested that adaptive air suspension would provide a smoother, more comfortable ride.

The air suspension option has to be purchasedon the Avant together with an uprated headlight system (bi-xenon or full LED) which makes the OTR price about the same as the A6 Allroad, which includes air suspension as standard. Would there be any difference in smoothness/comfort between these two models assuming the standard spec tyres are fitted (17-inch A6, 18-inch Allroad).
