I vote for #1. With the engine bay color, new roll bar and darker interior itwill look killer! I take it the whole reason for putting more money/time into the car is that you want a tuffer look...this will give you that!!
You say you want a PT look? I would say that's what you have now. What I understand you want is more of a g-machine look...but not totally street fighter.
Going to be some cool changes to an already killer car!!
