Approximately mid July 2015 Gearbox(es) went pop.
After recovery by green flag, the vehicle was pushed off the road, parked up next to the hedge and left.
MOT Expired 29/07/2015
fast forward to present day!
So, having trimmed the hedge back and cleared up a bit, today she moved for the first time since about July 2015. Just towed her out with the van, then rolled her back in front of the garage. Nice to see her out, now just got to get her fixed up.
