I have the Ultrasport A4 model, so the exterior styling is beautiful & agressive. It is a very classy car.
The interior is just amazing. Far superior to any other cars in its class (BMW, Lexus, Mercedes, etc.). The interior sets it apart from all others, & is why I chose it over all BMWs & Mercedes I test drove.
Very pleasureable driving experience. More driver engaged than Lexus. Lexus is very smooth (more than Audi), but to the point that the driver is really disconnected to what the car is doing, & it gets very boring quickly.
