In the affluent area I work in, Euro cars dominate the sedans, while the same families will have a good 'ole Suburban/Yukon (albeit with every available option) or Excursion (R.I.P.) (oh, lets not forget the Escalade)relagated to towing/family truckster duties. Unless that Audi has the wheelbase of a Suburban, I don't see it being a 'huge success' on the showroom floor. Around here, you rarely see any Touregs, Porsche Cayennes, etc despite the high HP options available. I saw a guy with a Dodge dually recently...nicely done letters on the back window..
