Drove one of these a few weeks ago. Not sure if it was 2015 or 2014, but if you have any luggage it's garbage. In order for the top to go down you have to adjust a bizarre shade in the trunk, severely cutting the trunk's capacity. Didn't realize this when I was at the rental location.
I currently have a 2015 or 2016 Mustang, which is much better in almost every aspect (especially when it comes to the trunk).
