simply put. This is the greatest thing I have ever seen on the internet

There's a little Metropolitan that shows up at local SoCal shows with a blown big-block Chevy. Has a more radical idle than that Valiant.
All he does is unload it off the trailer, idle it in and park it at the show. Same when he leaves. Never seen it run at anything more than an idle. Heard a story that one of the members of a local Mopar club told the owner to show up anytime at Irwindale to get his butt kicked by his street-driven Hemi Mopar. As far as I know, the Metro is just a poseur show car.
