KBB.com Review
Kbb.com Expert Rating
The 2018 Audi A7 and Audi S7 offer all the virtues of a roomy sedan wrapped in a sleek, coupe-like body. With two powerful engine choices, dynamic handling and what is arguably one of the most beautiful interiors ever crafted, it’s hard to find reasons not to like these two cars.
All that we love about the 2018 Audi A7 sedans comes at a rather lofty price. You can get the same style and performance from a less expensive Audi A6, BMW X4 or even a domestic like the Lincoln MKZ.
