I know what you mean. I still have this 'aversion' to foreign cars and I know it's just nostalgia. But then again, I'm still waiting for the Packard to come back. ;~))
Full disclosure: My dad worked for a Packard dealer when I was young. Dad told me that Cadillac was a swear word and those Caddys were only Chevys with chrome-plated lock washers.
Who's to argue with dad? ;~))
And damn, I wish I had that 38 Packard Roadster that was the first car I remember riding in.
