No, I do not agree Chris. Spain also produces hundreds of thousands of Citroëns every year since the Fifties and I do not dare to say that Xsaras, Picassos or Berlingos produced at Vigo plant are Spanish. Design and development are French (as well as the investment) so the cars are French, no matter where they are produced.
I work for a Japanese manufacturer here in my city. Any of the workers here, neither blue nor white collars, think that our vans and trucks are Spanish, although our plant remains in the same plot since 1957. Japanese made in Spain, we could say.
Spain manufactured thousands of Austin 1100, MG 1300, Austin Victoria, Minis and some other BL models at the plant of Landaben, Navarra, back in the Sixties and Seventies, also with some differences compared to those made in Britain. Would you say then that these cars were Spanish?
Well, maybe it is just a matter of culture difference, but for me (even being a car's professional) the place where the car is manufactured is not important. Important is the design, the development and, top of all, who puts the money on the table.
