Bluespit, there do seem to be a number of cars knocking around within your travel radius. However do you have some specific requirements such as colour, wheels, sat nav, auto/man etc that you haven't mention that are limiting factors. Do you not have anyone to "cover" for you at home if you found a car a little further a field. Would seem a shame to miss out on a car for the sake of an extra hour or so travel time.
