Metric has been part of automobile manufacture in the US for at least 25
years. Many GM cars are built and or designed overseas so it is just
natural to use metric. There was a recent thread about GM cars that are
Opel and Holden sold under other GM names. Going metric just makes life
simpler. Don't for get that some cars like the Toyota Vibe and Mitsubishi
Eagle are joint ventures coming down the same assembly line.
As for foreign cars if you live in Europe the US cars are foreign. Yes,
they are metric.
Keep them Whitworth wrenches though, they may become popular again.
