The only Mopar they've done that would interest most of us was an old Challenger, and all they did was drag it home and flip it. The problem is, as we all know so well, there's TONS of cool stuff you can do to most any Chevy or Ford, but when you get to 66-74 Mopars, that list gets really frigging short. You can redo a lot of cars a lot of ways, but once you start talking vintage Mopars there's some decent OEM stuff, but "cheap and available custom parts" and "vintage Mopar cars" are just two phrases that don't mix. GMG does stuff fast & cheap, and Mopars don't fit that formula very well.
Besides, I can just imagine the whailing and nashing of teeth if Rawlings drug home a nice Charger or Road Runner and let Aaron lower it, drop a 350 in it, and do all the other crap he loves to do to cars. Oh, how the hate mail would fly!
As for the commercials, I'm digging them. They are funny and cool, and like the Road Runner did in 68 might just expand Mopar appeal to a different group of people, and that can be nothing but a good thing after that horrible Ron Burgundy/Anchorman II fiasco of a marketing campaign. I think Will Ferrell and his mom were the only ones who saw that movie, and Fast & Loud is one of the most popular shows on cable.
