<prompt> Human: Wanted to see if anyone had any advice for me regarding my very soon purchase of a used vehicle from craigslist. My budget is 3500 but Im hoping to spend a little less and still a decent vehicle. Anyway Ive noticed that most of the sellers in my area are asking for much more than what the KBB! values the car at. For example one I looked at was a 1998 BMW 740i in good condition with 120,000 miles. The seller is asking 3500 but the KBB values it at 2500. Ive found this to be typical with most postings on there. Why the huge discrepancy, what resource are they using to value their car? So my question is two part. 1 Is KBB still a credibly source to use to value used cars and 2 How can I talk down a seller asking for more than was KBB values it?  <response>: KBB is a good starting place for discussion, as people tend to use that to figure out a fair price. If you want to talk someone down, the best strategy is to have fair comparisons. This keeps it from being just an emotional plea. That having been said, you can probably find a better more reliable car from a brand like Honda or Toyota for the same money. A BMW is probably not going to hold up as well for the same money, and your repair bills will be higher. It also may be why hes asking more; to the seller, its a nice car so should command a higher price.
