it depends on what you want out of the car. do you want to cam because racecar?

i had the xp and i was awesome! great street cam, car really should have came that way from the factory. now i have the IS3 cam and it too is awesome but not nice on the street as the xp was, i still love it though! after a while i will be going back to the xp or s1x for a daily driver and get some fuel economy back.
