I think its a great bike, Having a unrestored A10GF 1957 I agree that this bike disserve a healthy inspection and fixing what is needed no more.
The white seat is a matter of taste otherwise make it work and keep it safe.
Good luck to the buyer if he thinks like above if not he better be rich cause its going to cost a fair bit to restore to new condition.
