A good friend of mine is trying to buy a 07 Mazda 3i outside of richmond VA. She is trying to get it fairly loaded with sunroof and 6 disc, side airbags, etc. She has an offer at 17,800 and she is trying to get them down to 17 even but they wont budge. Can someone clue me in to if this is a good price or if she can expect to get down to 17? Thanks in advance!
