Never SORN'ed ... 15 years with Morgans and I always had them available for a good day, even in winter. Two of my previous Morgans had MOT's in February/March, and despite the thought crossing my mind to have the MOT dates moved, I never did which forced me out on the road to get the MOT done .....
Forced is the wrong word, it may have been cold and sometimes it was wet and slippery,

but it always put a smile on my face on a winters day.
Cheers .......... Pete
