I would definitely go by age. Rubber tends to rot. In fact, rubber belts seem to rot faster when they are not used much. Same thing with tires.
I just reread your post and realized what you got. I have the first year of that model, called the LTD. Mine was pretty much junk when I got it, and I had to do extensive modifications and fabricate a lot of parts to get it going again. Sounds like you got a good one. There seems to be one main weak point on the LTD/SEi, assuming all the electronics work. The fuel injection system has about 25' of different sizes and lengths of rubber hose on it, some of which you can't get to without removing the entire system. ALL of mine was rotted, and I had vacuum leaks everywhere. If your bike is running good, I would leave it alone. But if you have running issues, that is the first place I would look. Enjoy your new bike.
