The truth be said, it is solely up to the buyer to beware! Read everything, ask questions, never sign if you are unsure or feel uneasy about something. It usuallly happens when a buyer is over eager to get into the new ride! If you have signed you have purchased.
This is so true however it is amazing how a dealer will look at you like you are paranoid just because you want everything in writing. Then have every excuse in the book when they are trying to screw you. If you treat them like a crook right from the start they are insulted, but have no trouble screwing you after you have trusted them. I would rather have the upper hand and let them think I'm a jerk.
