I love the '62 Poncho Bubbletop look too!.
I've looked for info on these before as I remember seeing a Canadian '62 Poncho Bubbletop years ago and have searched since but never found anything on them being a factory reality..
A few US cars have been built, the eBay car and this car
http://www.carcraft.com/featuredvehi...ina/index.html are both 62's w/ '61 roofs also I'm pretty sure I read about a '61 w/ 62 quarters/front clip etc before too..
