Removable top over cab - or large sunroof/moonroof, t-roof like Pulsar NX

... I remember back then there was also a company that made a one piece polycarbonate roof/back window that was as close as you could get to a convertible without cutting the door frames.

They were called SuperDome

A tilt-up / removable sunroof would be terrific.

The Slate Truck's rear window appears to be removable. Removing both the sunroof and the rear window would create a convertible-ish experience. My family had a 1972 Corvette with T-tops and a removable rear window. Removing the window improved the T-top driving experience more than you might expect.

Honda Del Sol anyone?

I had a pulsar NX. It shared some of the 'modular' concepts the Slate is going for. I kinda miss that car.
