Rawze is correct, the dealer will simply milk your wallet and throw parts at it hoping something sticks, I have been there and done that, as many of us have here. I have plenty of stories, and then I found this site, was stubborn at first, and soon figured it out, and it was very very expensive... Tens of thousands of dollars, I had to learn the hard way. Don't be me.
