A report from the BBC has pointed out people don't really know where there cars come from. That means that the Envision is likely in the clear as the first Chinese-made car imported into the USA.
The BBC cites a Cars.com survey which tallied 28% of people questioned as saying they would only buy an "American made" car. Those same people did not know that the Volkswagen Passat is built in Chattanooga, TN, or that the BMW X5 is built in Greer, SC. Did they even know that the Chevrolet Trax was built in Bupyeong, South Korea.
And forget where the cars are produced, what about where they are designed? Subaru and Kia have design centres in the US. In other words, a import brand can be designed and built in the US. You should also consider where all of the components are coming from.
So the Envision may be imported from China, but where was it designed, where do all the parts come from, and how does it compare to every other vehicle sold in America.
