I think that you are going to be very uncomfortable on it. I recently rode one and I'm 5' 6", and I felt crunched up on it. It is a good bike to start on, but I think you will need something a little bigger, maybe an SV650, or something along those lines.
For that new of a bike with that few miles, the price seems really low. If it is in good condition with no problems, I would buy it. Just make sure that the seller isn't trying to get rid of it fast because of some major problem.
