I love roll up windows! You can crack them just a little in the rain if needed, without spending 5 distracting minutes trying to open them a quarter of an inch with power windows. If I has a choice all of my cars would have them. The only good thing I see in them is in a 4 door where you can't reach the rear windows and want to get a good flow of air going.
The '05 Toyota Tacoma I have from work is similar to your Nissans. No extras except what came from the factory ("styled" steel wheels, sliding rear window, and a CD player in the radio). I don't ever feel the need for power locks, windows, or more cup holders(it has 6 for some reason) and 2WD. The body has held up very well, where a deer ran into me on the fender some paint chipped off (around one square inch) 3 years ago. Today it has not spread, and remains surface rust. The frame is a different story though it's getting scaly. I wouldn't hesitate to buy one for personal use.
