I have them and I use the sh*t out of them
Our Yukon got plowed by a bulldozer when it was six months new
I wanted it totaled but they said "no, they will fix the whole thing like new and it's covered for life"
So now when anything isn't "like new" I take it in and get a free rental car and have them make it "like new"
the whole thing has been painted at least three times, new windows a few times, anything mechanical... I just say "Bulldozer" and they fix it
bet by now they wished they totaled it
