they're good fun, and you can make them go 45~50 for a couple hundred bucks. The Metropolitan is the same frame & engine (up to 2012 I think) and those can typically be found for a bit less, I wouldn't spend more than about $1200 for a good, clean ruckus but location can vary that

They look like a riot I had no idea you could make them go that fast though. I'm getting one for sure now. New toy goal for next summer!
