While an interesting concept, I'd probably like it a hair better if they grafted an Aerocoupe glass setup on it instead. IIRC, there were some customizing "kits" of sorts offered for a while that allowed you to do that for a Cutlass and a Regal. But not too many people were up for that at the time I guess. Kind of expensive. And although better than an F-body graft IMO, still, an aero Cutlass looked kinda stupid. Again, JMO. I think the 2+2 looks the best with the aero glass (but the side profile- ugh!), and the Monte, not so much. Thanks GM for not messing up the Cutlass like that. Not horrible, just don't personally care for the fastback look on a G-body.
Time Machine story....If I wanted a wobbly rear hatch, I'd just go back in time and buy me some more of those 3rd gen F-bodies. Ooh, that brings back some hideous memories. Back in that era, right after I picked up my then-new 82 Z28, I took it to a "customizing" shop that just got in some new aluminum "Shadow" 3-piece louvers for the new F-body hatchback. Had that installed rather than tint because the tinters would not guarantee the back window with defogger. Too many complex curves they said and the defogger...they didn't like that because of the "defogger lines" could make it look like crap. Got to remember, 40 years ago, window tint film SUCKED if it wasn't on a flat-ish window. Speaking of crap, that louver would rattle over bumps, it was hard to clean under it even though the center section lifted up. Bad design. (If you think that's bad, you should see the plastic one-piece louvers for the G-body 2-door notchback windows. WTF?)
Just say no:
Picture an 82 dark blue Z28 with T-tops...and THIS......ewww. What was I thinking?
If I had to choose between the two of them...I'd take the seasick crocodile. Just because you can, doesn't mean you should.
And just...just no. Stop.
