Has anyone successfully negotiated a discount on the MCU2 upgrade in the event their MCU1 fails under warranty? I would be happy to pay for a discounted MCU2 instead of a free warranty replacement MCU1. I have a hard time paying the full $2500 for the upgrade when that ultimately saves Tesla money on a warranty repair. Just $500 off would be fair since I think that's about what it costs them to fix MCU1.
