NAO Design's JL421 Badonkadonk.

"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. The interior is fully carpeted and cozy, with accent lighting and room for up to five people."

For $19,999.95 (what, they think the 5-cents will make a difference?), it’s a steal! Link
