Roock is legion amongst Porsche enthusiasts as being one of the most unscrupulously and dishonest "tuners" out there . For example, quite a few years ago, a friend of mine sent his newly purchased boxster to him to undergo a total conversion that included an engine swap, suspension upgrades, cosmetic changes ect... The experience that he had was nothing short of horrific !! The vehicle was never quite right. And after being in storage for years, he finally "unloaded" it. Interestingly, the same vehicle surfaced on this site a few months ago - now in the hands of a new owner. Apparently, he couldn't get the vehicle to perform right either, and in turn "unloaded" it as well. Unfortunately, you learned a lesson the hard way. Stay away from Roock !
