First off, No need for the double post. People already saw you other post, it has 166 views.
Second off, posting on a forum that's for Kia Owners, you have little or no chance of actually selling it quickly. Remember, most of us here already own a Kia. Your only chance is to rely on the few members that come asking advice on which car to buy. and even in that case, its a pretty small chance that they are from your area.
So sorry for everything, but you need to be patient, otherwise, I'd say Ebay it or Autotrader.
15,500 is a pretty good deal. If i had that option i might have took it.
$14,940 according to Edmunds so you're in the right territory for an asking price and may have to negotiate down. Hard to come up with a fair price on a year old Kia considering all of the warranty doesn't transfer.
