Looks like a good and clean bike. FYI, that's not the factory heated grips (not that it really matters), and the windscreen is aftermarket too. Looks like maybe a Cal-Sci.
I wouldn't worry about any problems, these bikes are rock solid. The 06's - 09's will have a recall soon for a electrical grounding problem, and that's really been the only problem on the Gen II's. There was also an ignition switch recall, and an ECU Altitude Fix recall which have been around for a while.
20k miles is pretty low miles for this bike too. Proof:

In fact, the only problem I see with this bike is the price, and even that's not too far off from what I would consider a fair deal. I never compare tax & license costs as those vary greatly across the country. But the $8399 + $250 bringing the effective price to $8649 is too high for me in this market. I'd want that at no more than $8k...maybe even something around $7600 or so.
check out some of the classifieds on this board too. I know there's an '08 in Northern Colorado...could make a good fly 'n ride! If you'd like, I can offer to go up and take a look at the bike too, just to make sure it's as advertised (I'm sure it is, but just in case):
