Up to you but what are you going to replace it with? Just bought my 21 as I was not going to trust the 23 "lottery" as if and when I would actually get a car built.
I was at a car show this weekend and a broker came over and started talking to me about my car. He made a serious off of $115,000.00 but I am not wanting to sell my Super Stock. I was just surprised at the offer to be honest.
