Most sellers are still trying to get $4500-5000 but I don't think their bikes are selling. Isn't importation a pain (by design)?i envy you so much... the bikes you listed are dirt cheap...
a new versys is over $9500 here (and has to be special order), the f800gs runs $21k, the 900adv close to $20k......
are those 2nd hand versys for under $4k widely available, say near port cities like miami or la?, at the prices you mention it could be worth the headache to import one.....
