[Tran]

This Slate SUV is on display at Atrium in Old Sacrament (posted by @phatboy7). First time I've seen the SUV kit top's rear window open with struts.

Still hopeful that Top without seats and rollbar will be available.

I would think it would. Considering they plan a cargo version that would be what you want with the windows blacked out or just having opaque panels in their place, and they try to reuse parts wherever possible.
Looking at the photos posted today, it looks like the rollbar seen here may be the frame of the rear of the fastback.

Any insight on how the window locks? Captured by the (locking) tailgate?
