Bit of a jobsworth here, or maybe his last day in the job.....
All of the recovery drivers I have met seemed to be very eager to get your pride and joy on that truck, almost the Dick Turpin style of persuasion, as with a broken down vehicle you are not really in a position to bargain. As for it not being roadworthy, even with a brand new MOT it will not comply with the rules and standards with the roof smacked in, no windscreen and the suspension ripped off after a major accident, and there seems to be no barrier to dragging those vehicles back to the compound.
Sav.. I can't get my head around your speedwatch results. Do you mean it is rare to find full compliance?
Swarfy.
Additional. UK rules. Does your newly purchased non runner need to be insured for you to tow it back home? In other words would the forces of Law and Order consider it illegal on a tow rope, but OK on a towing dolly?
