Reviewed a 2019 Audi A6 on Jul 22, 2025
This car came loaded with every feature I was looking for. Blind spot monitoring, adaptive cruise control, vented seat, ect. I definitely got what I paid for in a good way. I wish the outside of the car had a sleeker design.

The A6 Avant from 2010-2011 can do it all. Its a rare car that is a family hauler, mountain climber, and it puts a smile on your face every time you drive it.
