GUSSIE 2000--- No problem, guy. Glad I could help somewhat in your decision process.
The exterior/spoiler version roof panel of VX-CRAZY is actually a solid panel "Sunroof" (not a Moonroof). There is a disappointing factor about the exterior/spoiler version: When fully retracted OPEN, the roof panel does not totally clear the cut-out space and there'll be a substantial front partial lip of the roof panel that still hangs over into the rear of the opening. Thus, it never really fully opens per the available cut-out (very irritating).
The Webasto brand interior headliner version is a see-thru tinted glass retractable "Moonroof". Unlike the exterior/spoiler version, the Interior Headliner Moonroof version when open will fully retract within its inner sleeve housing totally exposing the entire roof cut-out to open-air (very nice).
Having said that, I guess it all boils down to which type of roof panel you prefer-- a Sunroof or a Moonroof. My personal preference is a see-thru tinted glass retractable "Moonroof". I really like having the visual openess of a Moonroof, the increased ambient light, and watching the rain pitter-patter on stormy days (but that's just me). The Webasto Moonroof also tilts-up in the rear as an air-vent in addition to fully open-air retraction.![]()
