please help look at this shelbygt500 with 625+ HP

hi look in ebay for a seller named madmax he is a dealer.
2008 shelby gt500 cobra.
i guess selling a shelby gt 500 with all the up grades 10g's in upgrades even the 626dyno'ed HP package. 20" shelby wheels, etc etc etc.
he has all the pictures to prove everything.
do you think it is worth the money?
i would like as many opinions as i can, since this will be my 1st shelby.
thanks, #1gorilla
