I'd rather have that minty late fazer thou than the mt mate, but that's just my humble opine
Especially given the trade in...they are always piss poor and fairly insulting, but what they offered you is appalling, no wonder they wouldn't say it to your face.
If you gotta wait til January anyhoo, why not hold off til spring bud? You are far more likely to sell it privately then, and the mt won't be the latest newest bestest etc so they will accept less than they will now for cash. It's gotta be worth holding out til then. My advice in no way reflects the fact that by spring I'm hoping I will have recovered financially enough to buy your bike btw....
