Small Car adds Big Time Realism to N Scale Layouts Known for its small size, Mini Coopers were popular all over Europe, but a bit too small for use in the U.S. However a few years ago, modern Mini Coopers hit the American market as a sporty subcompact. They've been a big hit in the U.S. since and are now seen everywhere. Add these retro-modern cars to your N Scale highway scenes with this two-pack from Herpa. It includes two differently decorated models complete with printed racing stripes and wheel rims.
