They have mainly disappeared now, but for many years the taxis in Hong Kong (Toyota Crowns) had a dual roof. On top of the regular roof, and separated by about an inch, was another roof. The idea was that the flow of air between the two roofs, as well as the shade, I guess, would make for a cooler car. Perhaps this was because there was no air conditioning, or to ease the burden on the air conditioner. I forget now, it was a long time ago. Ah, I found a picture: http://en.wikipedia.org/wiki/Taxicabs_of_Hong_Kong#/media/File:HK_Toyota_Co mfort_Red_Taxi.jpg Perhaps if this really works, you could find a wrecked Westy, cut off the roof, and put it on top of the existing roof. Might get you a mention in łThere, I fixed it.˛ (http://failblog.cheezburger.com/thereifixedit) :-) r
