Randy,
I purchased mine about a month ago, and based on the market that price seems about average - I would try 17k though. Personally, I decided I was going to shop all over the country in an effort to get exactly what I wanted. If you want to test drive the actual vehicle you are going to own however, I would buy that one. If you want to get the best price, in a certain color combo, with a certain amount of mileage I would buy from a place like carmax.com or autotrader.com. Just my two cents, but you can't go wrong with this car, I look out the window at mine every day and smile.
If it feels right do it and don't look back.
