I am looking at buying a Mazda 6 Sports Luxury, 2004-2006 period. I have seen a few advertised, but what is the difference between "Series 1" and "Series 2"? I really want an answer from someone who is very familiar with Mazda 6's. Thanks.
Also, is it true that Mazda 6 are made in the US and Mazda 3 in Japan? If so, what's the go there?
