YOU need to develop a little patience. It has been less than 3 hours since your first post.......and people don't just SIT on this site waiting to pounce on new questions. Well, MOST users don't anyway. Just from the pictures, which may be a poor representation of the actual situation, it appears to me that there is a very minor scrape to some under-carriage parts which might not affect the operation or integrity of the vehicle AT ALL. But you really need a second professional opinion. You might have a beef with the selling dealer .......but going after a previous owner: RIDICULOUS. P.S. And if you want quality answers from people in places like this, you NEED to pay attention and answer the questions that they pose. Not doing so is just rude.
