I agree, but would you buy a bike unseen? It's a big leap of faith.
I did from a frequent poster on here. AND got on the train 220 miles to Wales to collect AND rode home in the pouring rain and hail in February. Just have to accept that if there are faults it is tough titty.
Are you sure you are really determined to find a Bird?? There a literally tens of millions of them out there.
Wouldn't buy blind otherwise though.
