From what I've seen and heard the crazy challenges are there but I don't think they will be crazy big on the first season. The ones I did see got a good reaction from everyone so I think it'll do well. Wood and Ferrara are natural car guys, though kind of unknowns to most. Most importantly, none of the hosts are perfect and a lot of their natural reactions come through.
Looks like the first air date is Nov. 21st and that should be the episode I attended
