Why is it rubbish?
I did put "BUT when no-one wants to drive over" ... And presumably you aren't buying every gun offered for sale!
I would also suggest that you are in a minority and the majority of people will be put off by distance, time and cost UNLESS the item is rare, high-value or collectable.
I have also driven large distances for the 'right' item on numerous occasions as being in central Norfolk myself we are in the arse end of the country and usually a significant distance away from everything!... But for the majority of my purchases on here the factors above DO play a significant part in my purchasing decision.
