The second video is Tony Tomaselli's "rat rod" MKII Tiger, Tony is on the UK forum and on this one.
The stiletto and Californian were fastback version of the IMP's.. the sunbeam stiletto was the sporting version , 4 headlights and round dials and sports tune, Californian was the more luxury model... i've always had a soft spot for the sunbeam stiletto.. but very few here... they just look cool to me.. and you could always dro a modern suzuki or honda motorbike motor in with 6 speed transaxel.. imagine the speed!
