Typically when I think concept car I think outlandish, futuristic lines, over-the-top tech and impracticality.  The Jeep J-12 is the exact opposite.  The J-12’s design exudes old school charm and ruggedness.  The concept is based on the 2012 Wrangler Unlimited, has a 6 ft. cargo bed, a 3 inch suspension lift and 36 inch tires.
