I use a mixture of the Killer Bee range, Ainsty hooligans, the odd Foundry figure and some gangsters that Black Cat bases made under licence for my USA based scenrarios. Cars wise, I've got some old style minis, a flash limo for "the Boss", a couple of cop cars/vans, a transit van and an ice cream van (useful "cover" for the cops watching the place). These are the result of cheap toy/model shop purchases and keeping my eye on the boxes of odd die cast cars at car boot sales.
