Had to pick up a unit from the garage, got to the reception and the man behind the counter tells me that the unit has a leaking air valve and it is not road worthy, will get a ticket if I get stopped. Just sign this waiver and you can be on your way. Not on your life mate, not signing anything and not going anywhere near the unit, not roadworthy and this is a garage, apparently they haven't got the part. Called the yard and the full time driver signed and drove it. Got another one and had to go to Hayes to collect medical stuff and take it to Magna Park, that was the easiest part of the day. Couldn't believe my luck on the way home, M1 & M25 clear, couldn't say the same when I got in my car and got stuck in a huge jam.
