Sure.
Build a vehicle that you know can't make it through the Rubicon Trail, as all Jeep vehicles have historically done prior to introduction in the market. Devise a top-secret test, like driving over a 2x4 laid flat on the shop floor, to test traction and artuculation. Attach "Trail Rated" sticker to vehicle.
The XJ is not trail rated. It was out of production before DaimlerChrysler invented that particular marketing ploy. The XJ is Rubicon tested (the real thing).
