I love popping people's "Domestic v. Import" bubbles
Your post brings up a good point, that not all cars are what they seem. The line between import and domestic autos is so blurred now.
There was once a time when the badge on the hood told you the origin and manufacturer of a car. Now, in many cases, it is just a marketing tool.
Think the Pontiac Vibe is a nice looking American car? I'd agree with you, if it weren't a Toyota.
Remember the Ford Probe? It was really a Mazda.
Saab 9-2X? Looks strangely like a Subaru WRX.
How about that neat little Chevy, the Aveo? It's a Daewoo.
Isuzu Ascender? It's a GMC Envoy.
New Suzuki Grand Vitara? Based on the Chevy Equinox and Saturn Vue.
These are just a few examples.
