I own a 2012 KB Boss love the car, my buddy is looking at a 2013 Boss or the new Shelby. Big price difference I know! I am trying to convince him to buy the Boss and keep the extra 30k in the bank. When reading 0-60 numbers as well as 1/4 mile times the Boss is just about neck and neck with the Shelby. Would love to get your feedback to share with my buddy.
