It’s hard to guarantee anything that far into the future Andy, but I take the point and you’re right, it’s a difficult thing to quantify.
My own sentiment is that the target is that 80-90{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} of repairs should cost under £100 incl labour. Whether that’s possible or not remains to be seen and depends a lot on what actually fails on a machine that is over five years old.
I can tell you that if it were today that I were pricing a part that the door seal would certainly be less than £20, a door handle under a fiver, a PCB under £50 and a set of bearings about £8 or so, a pump under a tenner etc. etc.
How that pans out in five years is hard to say without the use of a good fortune teller but based on what I know today we’d probably be, on average, about 50{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} less expensive on spares at a rough guess, than most.
Bear in mind that many parts were always intended to be generic though so that most of you will already have a pump and brushes, if not bearings on the van and they are dead cheap. This was deliberate as it makes a first fix far more liable, which makes us far more profitable as well as leaving happy customers behind us.
