For me Audi interior designs are by far the best. It have all the features I was looking fore and more, and there are much mor features they you can get that my A6 doesn’t have since I got mine used, but Audi offers many more in new models. The most important was getting a 3.0T, I believe if you are getting in a luxury/Sport sedan you don’t really want to go with the smaller engine, the power is excellent especially when entering the highway with fast incoming traffic. I can go on and on about it, but the best is to do a good research and test drive it, then finding the right Exterior interior color combination that you like so you can enjoy driving this piece of engineering every time you get behind the wheel.
