in a seperate but king of related topic Bosch are doing something similar already with their odometer's ?
it looks like they and possibly other multinational giants are working away on blockchain and IOT

That's actually quite a cool application of blockchain. Could it be applied to monitor other mechanical wear or even automotive applications (oil changes, service history or wear life relating to engine revs). And how about tachographs?
tachographs would be an excellent one all right.
what is needed for tachographs is a tamper proof solution and the blockchain can provide that.
The wear life would tie back to the OP's question regarding car parts.
