I've looked at that BBB site and found the 2014 model which looks like the one in question. Parts in description are pretty similar to what's on this bike.
I've replaced the chain and large chainring and cables recently.
In terms of overall appearance, paint has some scratches, brake levers also, so I assume some crashes or 'solid' encounters in time.
And yes I agree, seller (friend or not) should set a price. However, in this case, I'm supposed to come up with an offer.
