I am considering purchase of a used D90. I would like to get an idea of how old it is. I am therefore wondering; what is the range of serial numbers that was produced? The first concern after verifying operation is of course how many shots are on the shutter. It would though also be nice to know where in the production run the camera in question was produced.
I can't tell you anything about serial numbers. But I wonder if it really tells you anything. I'm not aware that the D90 had any particular problems at any point during its life. So the reliability is likely to be the same for any unit regardless of date of manufacture, and the only thing that really matters is the shutter count and general condition.
I bought a low shutter count used D90 and it works flawlessly.

Good question. I did a lot of looking for used before I bought new. Mine has the GPS (although I do not think I'll use it) and I often wonder if that was available on the D90's when they first came out (2008+/-?).
As far as used, here, I believe Kijiji is your friend. I don't know where you are in Canada, but Toronto seems to have good pricing frequently, at least they did when I hunted.
All D90's have GPS capability in the firmware to mark images with GPS information. However, they require an external GPS receiver connected to it to gather the information from the satellites in order to actually be of use...
