Both of these cars are two of my favorites. It would be an extremely tough decision but I would end up taking the Ferrari. The reason I would choose the ferrari is that ferrari's are even more exotic than porsche's, and when people talk about how they would take the GT2 for performance reasons, while it is more of a race car, trust me there is no way that you would truly "need" anymore performance than the Ferrari. And come on people its a "FERRARI"!!! Alot of people can afford to buy porsches(boxsters, carreras) but almost nobody can afford to drive a Ferrari. Not saying that everyone can afford to buy a GT2, but just saying that ferraris are more rare. Anyways, they are both amazing cars!
