Let's start with that stunning Ford GT at the top. The word prototype should stand out to you here. This car was built by Ford to test the fitment of various components. Officially its vehicle identification number reads "004," but make no mistake, this was the very first second-generation Ford GT to be fitted with an engine. Note the license plate: CP 1, or Confirmation Prototype 1. This car was put together so early in the development stage, many parts weren't ready. The steering column is from a minivan, the headliner is made from aluminum, and the "clamshell"-style hood in back is made from carbon fiber -- on the production version, it was aluminum, which saved nearly $45,000 in production costs, per car.
