I have heard about this but not have not really looked into until now. I bought my car this year in August from Town+Country BMW and I did buy the extended warranty for it. It is a certified series car and if anything I was told that the turbos where covered by the sales guy. I am now understanding why the sales guy told me that after being on this forums. lol!
Managing to keep 3 cars, a house, a cat, and the wife! Oh ya and my sanity!
