Hello, I have been tormenting the wise people of this board for two weeks now, and so I wanted to offer some sort of resolution. I bought the GPz 550 as my first bike. The guy who transported and inspected it (Mark at Sydney Motorbike Network--can't recommend him highly enough for competitive prices, service and brain power) was surprised at its good nick and said, though he can't be certain, the state of the bike seems to back up the low KMs on the clock. So it looks like I got a good'un. The only so-so bit is the tank, which has lots of missing paint and a bit of surface rust. I will look into replacing or repainting it, depending on which is most worthwhile.
