Mazda sells 10 millionth car in America

The first car Mazda ever sold in America was the R100, a cute lil' two-door fastback that was, unsurprisingly, rotary-powered. The year was 1970. Iggy Pop had made that much explicitly clear with "1970." Just imagine how weird it must have been for Americans to wrap their minds around some tiny Japanese upstart, selling a car approximately the size of a 1970 Cadillac Fleetwood Brougham's wheelwell, powered by -- what's this, German technology?

Audi rolls out A3 lineup at the Los Angeles auto show

There's something about German automakers and model proliferation—it seems that if there is a niche to be filled, no matter how vanishingly small, a vehicle will be devised to fill it. If no niche is extant, they'll simply invent one, which is how we wound up with the unprompted X6. Audi's new A3 lineup, which debuted at the Los Angeles auto show and will begin its 18 month-long North American rollout spring 2014, seems incredibly rational by comparison.

Antique Automobile Club of America displays car collecting and its finest in Hershey

Searching for vintage car parts, literature, gas station collectables, or even a nice old car? The best place to look is the annual Antique Automobile Club of America (AACA) Fall National Meet, better known as “Hershey.” Now in its 55th year, it's the world's largest old car gathering, with an 1,800-car concours, more than 1,000 cars for sale in the “car corral,” and, best of all, an astounding 9,000 flea market spaces, chock full of more automotive artifacts than you can imagine, all scattered in no particular order on 85-plus acres--that's nearly 90 football fields--or “22 miles of aisles,” as Hershey devotees say. It takes a lot of walking, but walk we did for four days, for a close-up of this fascinating offshoot of the old-car hobby.
