Is there a difference between the parts for a Premier and the standard model?

What is your question?

I am trying to find a window regulator for my 2008 Mercury Mariner Premier. I just need to know if there is a difference between the Premier and the standard model when it comes to this part. I have found a few websites that allow me to choose the Premier option, yet other don't. So before I waste time and money, I just wanted to be sure. Thanks.
