1471 it Dunc..!?
should tell you the number...
you say he was northern, well he said he was... Did he sound it?
must be keen to go thru the rallye news to find your number.. I would be very suspicious.. as said could be genuine, but to be honest I would take precaution.. If he has your number, the chances are he has your address and maybe was confirming if you still have it/got it..
All that said, could be a nothing call, and genuinely interested..
Difficult one, just wait and see if he calls back..
You said an hour to get the car out.. I reckon you should be ok then..
