So my friend was parking my car in the garage and busted my passenger side mirror on my 2007 impala LS.

I need to get it fixed and am thinking it might be quite easy to replace it myself, and I might save a hundred bucks or more by not taking it to a shop.

Does anyone have any advice? I've looked on google and there are plenty of places that seem to sell mirrors that would work, but I don't have much experience to know that if I throw down $50-80 on a mirror if it will actually work.
