The Dodge Tomahawk can go 0 to 100 kph in about 2.5 seconds, and has a theoretical top speed of nearly 640 kph. JUST what I need to go to work...wait, I don't work...I need it to go to the grocery store...yeah, thats my story, and I'm sticking to it!

Rumors are, Chrysler sold the original Tomahawk concept and nine replicas for up to $555,000 each. Wonder if that would be covered under an "anti-depression theraputic device" expense by SSD?
