If you find an FS570 for that price, jump on it! I (hesitantly) had mine advertised a few months ago
for $7000., got many emails, but in the end, decided not to sell it. It's just too rare, & I like it too much! Good luck in your search.
One thought is since it has 2 sets of body work, what could I sell off the complete 2011 white plastic set for to offset my purchase?
Will most likely end up with something more common like Husqvarna SMR, or KTM SMC. Not in a rush, but also don't want to wait too long either.
