I'm not trying to be a smart-a$$ but what makes you think so? I have two 1999s, one of which I purchased new. Straight out of the box it was as smooth as any M70 I've owned or used. Since the one you're looking at is used, that means it's been cycled a few times. Why not handle it and give it a try? You might be surprised.
