i dont think 370z's are boats, but it seems so many cars today are bloated. i guess i'm used to driving a late 90's 240sx, where the car is decently sized but it's minimally bloated. i can see around me, and i can "feel" the car persay. the z i drove was really nice but i just didn't enjoy that it wasn't the easiest to see 360* in.
same with the mustangs and camaros. i still need to drive the camaro and challenger, but looking at them up close it just seems similar. just not a fan of the bigger cars.
the mustang interior is nice though. out of the 3, i will probably go for the mustang.
I pretty much agree with every thing here, since I also drive a late 90's 240sx and have had similar experiences.
I will say the 370 feels alot smaller than the 350. I like them alot more.
