I agree that many brands do not have wide availability. If you have to hunt
for a dealer, CR will probably not be reviewing them. They make a habit of testing product from normal distribution (no cherry picked samples).
BTW Volkswagen and many foreign
brands are now made (have manufacturing lines) here in the USA. Many American Brands
are made in Canada or Mexico
Don't fall into the 'buy American' (although Canada and Mexico are in 'North America'
) name trap.
