my guess is they meant 6" or the guy didnt really know. I am almost positive the ones they put on are 6" procomp lifts, usually 35" procomp tires and some procomp rims. the 6500 may be the price over the normal sticker value that they charge at the dealership if you were to buy it prelifted from them. If the local lift shop can do the 6" under warranty for you then that is your best bet. Just make sure the dealer won't screw you over later if you go to the local place.
