The Kawi has been dropped, look at the shot with the exhaust can scraped up. Doesn't really matter, though, if the plastic is good and can be reinstalled. If the plastic is broken or there's hardware missing, that would be hard to know about if you're not familiar with the bike specifically.
As for being dropped, who cares? There's not a bike out there that hasn't been. Not one. As long as it hasn't been tumbling through the air as it throws bits into space, being dropped is not that big a deal. That kind of wreck bends things like forks and swingarms and wheels.
I would avoid the BMW. Service will be serious $$$$$$$. For example, clutch service requires the entire back of the bike (wheel, shocks, swingarm, drive shaft, etc.) be removed to access the clutch. Even for much less involved service parts will be pricey.
