I finally got my Roadbots in the mail yesterday. They're terrific. In some ways, they top Alternators, though the Alts enjoy slightly greater articulation and sometimes better plastic. The chunks of car that come off generally serve as weapons or shields, which makes for less kibble. The Lambourghini's incredible, and I'm fairly impressed by the little models.
My reason for investing in the Roadbots, though, would be Grim... er, the Land Cruiser. Take a good look at his robot mode. Imagine the head painted black, the chest gold, and the shorts red. See it? Someone else had the same idea and posted pics. Not only does the idea work, but his sword has electronics that make it glow red.
By the way, you can get these guys for less and with next to no shipping here:

Shipping takes about three weeks. Everything arrived via UPS in tip-top shape. I'll probably post pictures once I have some painting done.
