Being a full day's drive from the Mexican border, I rarely see Mexican cars here. But this week, while attending a seminar, I saw this Audi A1 with Nuevo Leon (think Monterey) plates in a motel parking lot. I never even knew there was such a thing as an A1, as the A3 is the smallest Audi sold in America.
Here is a review of the regular A1, which competes with the Mini.
And here is a review of the A1 Quattro, which Viva Chile introduced me to. Only 333 of them were ever made.
