Thanks, Nancy - er I mean Paul - after I posted that question I came across a review which gave the same figures you've given above. I would like to put an offer in but not sure when I'll be up that end of the M4 next. At least once a month, usually, I come up the M4 and cut through Bracknell to the M3 and the south east but no immediate trips planned. Will be in touch a soon as I know anything.
