Hi, I am a newbie to this forum and I thought it would be a great place to value the price of my 2008 Ford Mustang Shelby GT-C. I used KBB, but I am sure it does not accurately reflect the value of my car. It is No. 114 of 215 with only 13.5K Miles. 5 Speed Manual and in Excellent condition. Upgraded with 20" custom wheels and panhard bar. Always a California car. I would like to know what would be the value of my Mustang. Thanks
