Weekend Motorsports Roundup: March 9-10, 2013

Welcome to the Jalopnik Weekend Motorsports Roundup, where we let you know what's going on in the world of racing, where you can see it, and talk about it all in one convenient place. Where else would you want to spend your weekend?

Just one more week until the start of the 2013 Formula One season! Are you guys super excited? I know I am. Until then, we have a pretty decent weekend of racing on tap, including NASCAR at Las Vegas and a replay of last week's Grand-Am festivities at the Circuit of the Americas in Austin, in case you missed that.

As always, let us know about anything we missed, or about good livestreams out there, in the comments.
