For reference I own a 2008 MX5 and 2010 Mazda5. I'm thinking of buying a 2016 Mazda6 GT to replace the 5. I want the GT because I'm paralyzed so I must drive an automatic but I want the paddle shifters. One of my main questions is the ride comfort. This vehicle will spend most of its life on the interstate. How is the road noise and wind noise? I don't expect Lexus quiet but I don't want to be annoyed on a long trip. Also, are owners really getting 38 mpg on the highway?
