Take it to the council, they don't have a financial incentive to fail it.
It used to be the same at the old Hospital (before replacement with the new one), as WYMAS (West Yorkshire Metropolitan Ambulance Service) had their local workshops on site
They moved out in 2008, the new Hospital opened in 2010, & now based at Birkenshaw, & simply YAS now (covering all 4 counties, as Yorkshire Ambulance Service)
Staff could drop a car in, before starting work (if they weren't open, keys in a secure box) then collect a repaired/MOT tested car later in the day
Equally payment could be taken there & then, or the relevant forms filled out that were sent to payroll (& it deducted over the next couple of months(
Female (& anyone not too mechanically minded) staff were happy to use them, as they felt that they'd not be messed about/charged for mythical issues, as the mechanics were paid for fixing ambulances & cars were secondary to that (& might be delayed in ordered to get an Ambo back on the road)
I used them many a time, as did my wife, when any cars that we had were out of warranty
Plus, if we agreed to replace, if lost/damaged/etc.. whilst in our care, we could borrow tools from the engineers/'works-yard'
In the past, I think I borrowed chainsaw/9" angle-grinder/SDS drill (before I bought my own) & other items
Not any more!!!
I asked if I could have a length of metal conduiting that was going in the skip, only just over a yard of it, & was told "No"
Then again, there's ntot many left from that era, a couple of the 'sparkies' & one of the painters
