Here as a link to YouTube where an F250 aluminum body was in a wreck. Pretty interesting. It also stated that GM will be going to aluminum in 2019. Big Truck Big RV
Wasn't it either the Pontiac Fiero or Saturn cars that had plastic body panels? Didn't hear much of an uproar then and both were GM cars. Well I take that back. I do recall now about parking A Ford 6.4 Powerstroke (?) next to a plastic panel car and when the truck went into re-gen it would throw flames out and thus melt the plastic.
