I can't imagine an alloy without center cap. How can you balance a wheel without the centerbore?
Perhaps low end Fit will have wheel covers secured by lugs like typical Hondas.
Fits are only build in Japan,China, Thailand and Brazil. It's almost at the end of its model year. Honda may produce the next gen. Fit in US (very likely due to high fuel price).
