Wouldn't be for me, I would just be too worried that people beat the heck out of it and you know from time to time it was, especially in 20k miles. Unless you are getting it really cheap, I think I would look for a different used bike if that's what you are looking for with a few less miles. Just my .02
My experience is that buying the cheapest one you can find doesn't always make it the cheapest one to keep. That seems to apply to most things. Wives too probably. The bike that gets babied by the previous owner doesn't cost very much more than the one that doesn't.
