Same thing with car parts. I do not remember the exact figures but I remember reading an automotive publication about a Chevy Citation back in the 1980s.
The price of a new Citation at the time was roughly 6500 dollars new on the lot.
If the writers went in to the dealer parts counter and bought all the parts needed to assemble that Citation the cost was right at 90k dollars.
Parts alone; no labor factor in that 90k. Kind of shows just how cheaply parts can be manufactured.
