Almost convinced to get the 370z..couple of quiestions

[Rich1]

So I'm close to getting the 370z but had a couple of hang ups and was wondering how other owners were dealing with the issue.

1. Door handles: I know they are unique to the Z but with the way that they open do you have any issues on a day to day basis when you're carrying something like a drink.
2. Door edges: The door edge which is a bit sharp from the trim sticks out a bit from the window edge. Has it ever cause any issues when you accidently scraped yourself?
3. Accessing behind the seat: I know that I'm not buy the Z for storage but on the models I've checked out there doesn't seem to be a quick way to access the little nook behind the seat for storage. Is the leaning into the car and across the seat to reach the power seats the only way?
4. Rear view - How do you find the visibility out the back? I noticed because of the slope it seems quite limited.

Any advice on the above would be great. Thanks!
