In the case of a Defender bullbar, I'd agree. The Defender doesn't require any relocation, styling is easy, no airbags and the exact same design can be used for many, many version of the car, and there are a lot of people wanting it so sales volumes are high. None of those factors apply to the D3 or similar vehicles which are harder to design for and far, far lower volumes. That's why you struggle to find modern Range Rover accessories; if the manufacturers thought they could make a buck there they would, but the demand doesn't exist.
