This is a great little car. Have had it for 7 months and am very pleased with it. I bought it primarily for it's fuel efficiency and not disappointed, averaging 45 mpg hwy & 37 city. Car is comfortable, quiet and has fairly good handling. The A3 has a clean exterior (sport wagon look) and a well laid out interior. Audi builds a quality car and while the A3 is their entry level vehicle, my opinion is that they did a fine job with the A3. It is pricier than the VW Jetta TDI but the detail level between the cars warrants the higher price.
Fuel and exhaust emission efficiency. DSG transmission is major improvement over Tiptronic. Bluetooth software. Ride quality for vehicle size.
Rear seats should fold flat vice at a slightly elevated angle.
