Re: Integrated Costs
"Why does everyone assume that everything they own must be repairable."
Go away, sit in a dark room somewhere for a while, come back and re-read that sentence.
Then slap your face with your palm.
I've just repaired someone's MG ZR, literally just yesterday. It would have cost them a shedload of money to get a broken keyfob replaced, without which the ECU would point-blank refuse to start the car. It took me 10 minutes with a soldering iron on some broken battery contacts, and 30 seconds pressing a reset-my-shit button sequence on the keyfob while stood next to a blaring car alarm. Cost effectively nothing.
I'm sure you'd rather this person just go to a dealership and get raped for a new dongle by people quick to spot, and apply taxes, to idiots.
