This is an interesting set. I like that it is using generations molds. If you ar eon the fence, I JUST reviewed the Challenge at Cybertron version of Hot Rod, with a few custom paint apps. I don't have Wreck gar yet, but hey, if you want to know how Hot Rod stacks up, check it out. Personally, I think he is the best CHUG version going at the moment. He IS aging and does need to be updated though.
