You can get sets of these from Amazon or Ebay between 10 to 12 Dollars or pick them up at Micheals craft store for about the same.
I'm only going to talk about those in the set that will work for 15mm gaming.
Okay so the Police Car, Pickup Truck, Mustang and Delivery Van are just the right size.
I really like the looks of these, the bodies seems to be of a rigid rubbery material, and the chassis as well. A good repaint would make them look better.
Here are some repainted from Welcome to Lazarus blog http://welcometolazarus.blogspot.com/
After seeing those I knew I had to have some myself, I compaired them to the 1/100 scale cars that I have and they will look good on the table.
I want to have more of the Police Car, Pickup Truck, and Delivery Truck. not sure if I would buy more of these sets just to have three vehicles out ot the set I'm leaning to just make molds of them and cast them. I want to have a few more Police cars and use the Delivery van and Pickup as support vehicles for the Police cars. I want a couple more Delivery vans for other uses UPS truck, Mail truck and other delivery trucks and what's wrong with having a handfull of pickup trucks.
But that all will have to wait for another day, will be moving the first of the month with any luck.
