Re:
This won’t help you, but I wanted to add my voice to d8mok’s, mtbdave and MTS's view.
I’m 62 years old, and have been doing this a long time now. I remain astonished and disappoint that there are people on here doing this “thing that we do” for any sort of investment or even profit. This is a hobby and an interest, and those pastimes cost money. It is money well spent in my view.
Like d8mok, mtbdave and MTS said, if you are concerned that “the arse falls out of the value of bikes and parts”, then put your money into proper investment – even dig up your lawn or tear up your driveway and grow some vegetables to sell – that would be worthwhile. Just saying.
