I get the impression that you are looking for someone to come up with a value higher than $14K. No offense, but that is probably all the money for this car. I too drive a 3.2 and although my miles are lower, I would be looking at about the same, as mine is a Targa. I am sure your car is in great shape, but the unfortunate part is these are just not that rare.
Best of luck. Personally, I would keep it for a while longer and see what the market does.
