I do like the look of these. I'm not really sure that they make financial sense but I think the exclusivity would be ace. Infiniti have none of the negative stereotypes attached to them that you'll get with a BMW or Audi (or Partridge associations of Lexus ) and you may just get flashed out of junctions.
When I replaced all the Nissan badges with Zed badges on my old 350, I used to love watching folk wandering round it trying to work out what it was. You wouldn't even have to change the badges, Stan!
