My card doesn't shake or do those things why would I need the bushings replaced?

What is your question?

I just had a front end alignment about a year or a year and a half ago and the guy tells me that I need lower arm bushings replaced my car doesn't seem like it has those problems. I don't drive it that far and I take care of it so do you think he told me this because I would not know what he is talking about? Do you think I should get a second opinion? thanks
