The trunk area of the Miata is designed much better than the Sky - it actually has a usable trunk. They did this by extending the interior beyond the seatbacks and placed the roof in this space. This allowed them to have a conventional trunk. On the Sky, the interior space ends right behind the seatbacks, forcing the roof to take up all the trunk space. Placing the trunk hinges in the back took up any remaining trunk space. Not a smart design at all. They had a good package design to use - the Miata design - why didn't they use it?
