I hate to burst your bubble but thats not really a "good" deal. Its a fair deal but not that great.

You'd have to go to modesto but it might be a better deal. General rule of thumb for me is to NOT buy from the bay area due to inflated prices. I bought my S2R 800 (05) last year with 1200 miles on it from a guy in sacramento for 6250,

Ask questions, be patient and best of luck.
