Geoff is an amazing electrical vehicle built by the 3 greatest people to ever live (aka Richard Hammond, James May, and Jeremy Clarkson. 
Here are the stats that I totally didn't just take from the wiki.

A single electric engine and two batteries, scavenged from a milk float by May.
A horrid, shiny exterior that can blind someone (featuring the windscreen from a Land Rover), three lawn chairs for seating, and a Roof Box made by Jeremy.
A chassis "made" by Richard. He actually took the chassis from a TVR, in order to save time and money by getting through the EU's red tape.
