I like the old school tractor style wheels but I'd swear the body panels look like plastic?
Plastic? Plastic? You mean like less weight and no rust plastic? What would be wrong with that?
I remember see one piece AFTERMARKET front ends on old Land Cruisers in the 80's (probably Fiberglass), they reduced the weight by 100's of pounds. I think 400lbs!
In the prototype days, they were after the GP to be 800 pounds or under, and never made it that low even with an Aluminum skin. They might now with a polymer or fiberglass body. They won't hold up well bumping into trees! But that only happens in the woods & less than 10% of Jeeps ever see a trail these days!
As to the CJ-5 rollover problems, I was driving from Columbus, Ohio to Clarksburg, W Va. in the summer of 1975 on US 33, Every few miles (in W.Va.) was an AMC/Jeep Dealership, in every lot was one or two rolled Jeeps! I stopped and looked inside 3 or 4, to see if they had any of the basic off-roading equipment. Nope they were all showroom stock, driven by "wannabees" who never thought about how to turn 90% going downhill on a 30% grade! And most likely took is at 35 or 40 MPH!!!...I never saw any sign of fatalities, but the insurance companies were screaming bloody murder! And because of that stupid stuff, we ended up with the CJ-8, a Jeep looking vehicle whit the wheel base of a Cherokee! VERY, VERY, VERY stable, but turns like an 18 wheeler! I drove a 74 K-5 Blazer (also the same wheelbase as a Cherokee, but 1.5" better ground clearance with the same tires) and I got around fine! I understood how to drive off road!
