Additionally,
here are some free counters provided by SJ Games for use with Car Wars 5th edition. They'll be at 3x scale for original car wars.
The scales for the above:
- Car Wars 5th edition - 3x scale (1" = 5 feet - same as most maps for D&D 3rd edition and beyond)
- GURPS Autoduel - 5x Car Wars scale (1" = 3 feet)
- Autoduel Champions scale - 2ish times Car Wars scale (1" = 2m)
- Original Car Wars scale - 1" = 15 feet (for the sake of completeness)
