I was going to get the new Camaro but started looking at the A5 and S5. Then I was offered a test drive in an S4 STaSIS.... I purchased the car the next day and have had no regrets! The power and handling are amazing! I can't imagine having an Audi and not having STaSIS! My interactions with STaSIS employees thus far has been great! Very helpful and are willing to answer every question I have for them! My fiancé and I have enjoyed it so much that we had STaSIS touring installed in her Q5! I can't wait to have the V2 installed!
