I thought these accessories were ones requested and paid for by the motability customer, on top of the AP?
I could be wrong, but have never been offered a dashcam for free.
The dead giveaway is the £20 in fuel you have to pay the dealership. The cars are delivered on fumes and to make sure you do not run out if fuel when you leave the garage, they put £20 of fuel in, which of course you must pay. It is not Motability that pays this, but the customer.
