Don't Pay for Pre-Assembly
They sent me a go kart that was stuck in reverse. It was a nice go kart, but it was stuck in reverse. They eventually offered to refund the $250 assembly fee or to let me return the go kart for a 75% refund (in order to cover the shipping cost to return it).
Their customer support personnel did try to address my concerns, although they were hard to contact sometimes, and did all they could to satisfy me within the limits of their company policy.
A mechanic told me that fixing the go kart's gear shift would take about 20 minutes, but that it was fixable. The go kart was very nice, except for the gear shift stuck in reverse.
My advice is that if you by a go kart from these folks, do not pay to have it pre-assembled. Just have them ship it and then pay a local small-engine mechanic to assembly it for you.
