Apologies if modern (2013) toy cars don't "belong" on LRG, but these are kinda cool and only £1 each!
I picked up one complete set of cars 1-10 and will most likely grab another set to open (and then chase down the "chase" versions and play sets on eBay, turning a cheap collection into a pricey one )

They're pretty darned cool
