The S4 has more than enough performance as expected. Handling, comfort are all excellent. Adaptive cruise control has been improved over our other Audi, 2018 Q5. This was a pre-order and the price was about the same as a 2018. Very nice car, delivered with no discrepancies. First 3,000 miles have been trouble free. Dealer service, when needed has been excellent (routine checks only on a 2018 Q5).
