Why would you drive a manual in traffic?
From a collector standpoint, I would think the manual will be more valuable many years from now. I bought mine because I have an older model Z that is a manual as well and I just like the feel of it. Am I faster with a manual, no. But, it's difficult to put this into words - with the manual, I just feel like I'm more involved in the overall process of driving the car - in an automatic, I'm just the guy steering the wheel. My ideal situation would be to own 2!
