That happens alot on craigslist. Most of the scam emails they will want to send you 15,000 for a 7,500 vehicle and then they will tell you to give the rest to the shipper. They will also say "is this item still available" instead of what you got!! You have to be careful on craigslist. you will fake emails 'from them saying your account has been suspended ( when really it hasn't). I did that once and they got my password and started posting cars and other items on my name that did not belong to me.
