The JL421 Badonkadonk is a completely unique, extremely rare land vehicle and battle tank.
Designed with versatility in mind, the Donk can transport cargo or a crew of five internally or on the roof, and can be piloted from within the armored shell or from an exposed standing position through the hatch, thanks to special one-way steel mesh armor windows and a control stick that pivots up and down to allow piloting from the standing or seated positions.
Tragically, not street legal.
Via Amazon for $19,,999.95. Carries cargo or a crew of up to five internally and on the roof. Might be a little snug, though the 400 watt sound system with PA might make up for that.
