Is the Yaris engine a little rough?

[thomasward00]

I guess i'm used to larger smoother cars, my yaris has less than 3k miles on it and I can feel it vibrate through the steering wheel a little bit, even more so with the A/C on. When looking at the engine while running, it moves around quite a bit. I brought it in to my local toyota dealership and the mechanic looked at it and told me that these small engines just vibrate a good bit and not too worry. He told me that if something is wrong that the check engine light would come on. I guess i'm just used to the smoothness of my other car, caddy with a northstar V8. Does anyone else notice this also?
