I guess you could ask the same question about Honda/Acura, Toyota/Lexus, Nissan/Infinity or Chevy/Buick/Cadillac.
We ordered an MKX not because it was $10K more than the Edge, but because it was $5-15K less expensive than comparable CUV's from BMW, Audi, Lexus, Infinity, LR, VW, etc...
And it was built by a North American company that isn't owned by the government.
