I know the differences between the first year 12-13 models, just wondering for those of you that have 13-15 models if there are any differences. For those that have Touring and GT models, do you like the bluetooth speaker set up? Also wondering if the Sport models have a USB and aux jack, as I get conflicting info. My 08 has 169k and I want to be ready to pounce on a newer one when the time comes.
