I work for Porsche as a detailer and let me just say... that kind of maintenance is NOT cheap at ALLL.. To put things in perspective.. A BOXSTER (cheapest Porsche to own) engine costs about $14,000.. This is a Carrera GT... probably THE most expensive Porsche to ever own. Granted, they didnt replace the engine. I just wanted to put the cost of parts in perspective for ya lol
