i seen one too! it had quad turbos running 43psi, he would not let me see under his hood either but he had a sticker on the side of his car saying "this is for real, it has 4 turbos and 43psi and is super fast and it is a super rare top secret limited porsche edition". It was a really long sticker that ran from the front fender to the rear fender but it looked legit.

wow was that thing crazy.
