I just sent mine in today. I called my dealer to see what the UIM goes for so I'd know how much to insure it for. Guess what, boys and girls, $816.00!! I could get it for less through my son's account (around $646) which is still a ton of cash. I couldn't believe it, I checked twice with 2 different people, same cost. So, make sure you insure your UIM, it'll cost you a body part to replace it.
