The cars are best suited for burnt out wreck terrain. If you want cars that will function as scale cars; try an ebay search for Maisto, or Matchbox Yesteryear, Solido, Corgi, Jada, or New-Ray. In my experience the new ray cars are the cheapest and scale very well at 1/43-1/48. I have tons of new ray, jada and maisto cheapies that I use for many games. You can get most periods of car models as well. I have some 50's American makes and some moderns as well as some old-timey gangster cars.
