Best Ad I've Seen this Season

So, I'm kinda puttering around today, fixin' a roast beef dinner. The kids are coming over!
In the background, the Great American Race is on the TV.

The Super Bowl gets all the hype, but the Daytona 500 consistently has the best ads.

Today, I was watching the girl, in the passenger seat, wax poetic how about how great their relationship is, and how her parents love him, and how even her cats love him, and how she wants to spend the rest of her life with him...

Meanwhile, the poor guy who is driving, is nervously watching the Check Engine light burn bright red, and not really paying attention to anything his girl is saying.

He finally decides he better pull over, while she natters on....

Of course, he pulls over right in front of a jeweler's store with a big ad for diamond engagement rings.

The ad ends with her on the cell phone telling someone (Mom?) that she is getting married while the guy rolls his eyes and bangs his head back against the headrest of his car.

Once I got done laughing, I realized I had absolutely no idea what the ad was advertising!!
That's ok with me, it's the best ad I've seen all year!
