Wow. I can't believe some of the responses. Some of you are still living in the past.
Regardless, let the guy try to sell his car. It's not a bad price for what he's offering. Also, when you're talking about thousands of $'s, these things may take some time to sell. If he sold it within a week, then his price was too low. It's a lose/lose situation. If the OP doesn't sell it because he's asking $10,500, how does that hurt you? Just let the guy sell his car without the criticism. If he's asking too much, he'll figure it out in time.
IMO though, this is where the market is headed. It's not an unreasonable price, flip or not.
