Well, they're great bikes. I had a '97 with only 10k miles. They were virtually unchanged except for paint and graphics from '88 thru 2007 so everything is interchangeable and you don't really need to pay attention to the year, just the condition of the one YOU'RE looking at.
They're typically beginner bikes, so they do suffer the 'dropsies' - bent levers, broken mirrors/blinkers/plastics and sometimes poor maintenance.
But, they're still great. Mine would pull me well over 100mph and still get 70+ mpg on my daily commute.
So, around here, 1600 might be a shade pricey, especially for one that will need carbs cleaned from sitting and has broken plastic. Mine was in great shape, no 'beginner' issues and I sold it for 1300 after a month on craigslist.
Good luck with it, whichever way you go.
