in the case of the Audi's and VWs, try the new A4's i believe, they're just little squares. (maybe not the new new A4s, but on a farily new model i think)
and about the landrovers, i have no idea, never heard of anyone doing 'em, usually people stick w/ audis (at least i think so) because contour's lines and style is sort of simliar to that look, so the side markers will fit well
