Wow a 2010 with only 9800 miles on it is incredible. I just happen town one also that stays garaged and I still managed to put 27,000 miles on mine. As far as what to look out for. From what I've been told there have been several shimmy incidents. Some people have posted that their leather has cracked, sunroof came off track, navi, isn't really that good. When I purchased mine for my wife, I factored in exactly what she needed just to play it safe. No sunroof as I wanted no chance of leakage, no navi since to be it wasn't really that impressive. No rear spoiler to keep that back clean and simple.
Overall it brings a smile to my face whenever I get to drive it. So I would runa car fax on this one, get a warranty if offered, and just because it only has 9800 miles, doesn't make it less of a used car. So don't let them convince you to pay new car price for it..
