They are rare trust me, I drive for a living, pounding the highways ten hours per day and I've only seen a handful.
Having one on order, I'm looking out for them all the time. I've got a great view also of the opposite carriageway!!
Now my last set of Wheels; Nissan Navara Aventura, now they are every other car!
I reckon you're likely to see them at dealers don't you?
