a stock car race
Why do you call it 'stock' ?
NASCAR is the National Association of Stock Car Auto Racing.

I was going to send you to the NASCAR site, but their site is terrible if you're not already a fan. I've been told that stock car racing is the most-watched sport in the US. I"m not a fan, but a close friend is a HUGE fan.
