"My 2009 challenge edition A4 Avant is awesome. The power, handling, and ride set-up put this car on par with many exotics. The best part is that the car is extremely functional while maintaining better than factory level comfort. The power is amazing across the entire power band and the car corners like a slot car racer. The overall driving experience is truly amazing and thoroughly enjoyable. This car is the best daily driver I have ever owned. STaSIS has done to the A4 what Audi should have done out of the box. The car attracts a lot of attention as well.....you should see the looks I get whether driving down the street or at Coffee and Cars on the weekends. STaSIS has created what I call Understated Elegance with Loads of Performance at its finest. Truly amazing!!!!"
