im not a sci-fi fan myself, but my dad and me being the car geeks we are, when i was younger we had a dinky/corgi/spot-on/tekno etc. model car collection. my dad's mate runs a collectors shop in Bridgenorth, and deals in all sort of collectible stuff as far as im aware.
shop is called 'The Toy Emporium', on the Bridgenorth high street in high-town.
i sell a few from time to time on eBay, seem to get best prices on there
