Questions for the seller (2)
Battery health report The seller can pull one from the car; it's the only real degradation data, and nothing remote can measure it.
Build date (door-jamb sticker) and original in-service date Settles mid-year running changes; the in-service date, not the model year, starts the warranty clock.
