Well the 240 is probably going to be cheaper in the long run but I love my NA. It isn't the fastest car in the world but it sure handles and it is faster than most stateside 240s. Not to mention the looks you get in the Z. The 240 is a very nice handling car, it's looks are sharp and they can be had for pretty cheap! The only thing really is make sure if you get a Z that it is checked out before you purchase. The less problems that it has when you buy it, the less headache down the road...
