What is this song/music video?

I watched it a while ago on my music choice on demand channel, but I can't remember it. The band is a hard rock group, and the video takes place at a car repair shop. Anyway, the guy is sitting in his car, and I think he was spying on his girlfriend, who is kissing one of the guys who works at the repair shop. I want to say the band is just 3 guys, but I could be wrong on that. It's a longshot, but if someone gets it, I would be ecstatic. Thanks.
