My A8 L is a 2017 3.0T quattro Tiptronic with everything including the adaptive chassis and front power seats with massage. In other words, you really can't beat this care for comfort. Even the controls are laid out in a configuration that makes sense and with easy access so your fingers don't fumble around when you want to reach out for something. The highest compliment I can give this car is that I actual enjoy being a passenger when my wife is driving. Not that my wife is a bad driver, but usually I am a horrible passenger. The ride is amazingly smooth and acceleration is close to driving a sports car. The safety features are amazing and should you be using lane assist, you will get an audible warning to tell you to put your hands back on the wheel. Some people aren't fans of all the safety features but I am. Given the condition of roads and the amount of distracted drivers out there, I like feeling I might have an edge. The navigation system is excellent and it also provides you with traffic conditions and problems ahead. I did purchase extended warranties guaranteeing me bumper to bumper protection through 2023, including scratch protection. These automobiles are really comfortable computers on wheels and only a fool would fail to protect themselves in case a computer board or chip gets fried. My collision insurance took a slight jump as these wouldn't be inexpensive cars to repair, but it wasn't a bump such that it is highly noticeable; more like a hundred dollar jump.
