Perhaps inspired by Ford's sales of a few thousand California Special Mustangs here in the US of A, Hillman decided that slapping the name of Richard Nixon's home state on a fastback '67 Imp would somehow convince legions of British car buyers to part with 650 for the thing. Sadly, the Imp Californian lacked the hotter Sport engine used in the Super Imp, and sales were disappointing. I'm still trying to find more details on the '71 Manson Family Edition Imp.
