I just looked at the lease programs on the Chevrolet website for the Volt. One of them included this qualification, “Current Owners and Lessees of 1999 or newer Daewoo, Daihatsu, Honda, Hyundai, Isuzu, Kia, Mazda, Mitsubishi, Nissan, Scion, Subaru, Suzuki and Toyota vehicles”, It sounds like they want to attract people who normally buy Japanese cars.
Pretty mean feat driving a Daihatsu newer than 1999, considering they pulled out of the US 1992-1993 or so.
In our global economy, most Toyotas are almost completely made in the US. Meanwhile many “American” cars are made elsewhere. Chevrolet seems maybe better than Ford, but e.g. the Avalanche is Mexican.
It’s not a matter of country of origin, but that some car buyers only ever buy one brand’s cars. My last three cars, for instance, were Hondas. Some people only ever buy Ford pickups, rather than GMs.
