I had the Hammerhead GTS150 version of those China Karts. I got it for $400 running like new from a family that was downsizing there living style down here in Miami, FL. It was a lot of fun until the cheap frame started to rust out. Ran it until it wasn't worth it anymore. I can say I got my $400 out of it for the 3 years I owned. It's crazy how those karts are at or above $2k new.
