The 2020 Ford Shelby GT 500 starts out at $72,900 or about $1,300 a month if you have amazing credit thats some $12,460 more expensive than the base GT350 and $535 cheaper than the GT350R. Does it blow your mind to know that the GT500 can be customized to the extent that it will set you back $107,080? Just how the hell do you add $34,100 worth of options to a freaking Mustang especially the, arguably, best Mustang you can buy? Well, as I was customizing mine, I noticed something the GT500 has a $10,000 racing stripe option, one that is now available next to the usual $1,000 vinal stripe. How does Ford justify charging $10,000 for a racing stripe that, regardless of what you think, doesnt make you go faster? Well, heres the deal.
