Well it's kind of reached a stalemate with the original seller (waves in case he's reading). His description was:
This bike is over 12 months and shows signs of general use i.e cable wear, small scratches and chips. However there is no serious damage, cracks, deep scratches etc.
None of his photos showed either of these two areas of the frame.
So my motivation for posting this thread was to get some second opinions as to whether either of these two marks were serious enough to worry about and therefore whether or not they were contrary to his original description.
The seller is sticking to his guns and refuses to admit there was anything incorrect in his advert. So now I'm stuck
