“Whatever we have, you now have,” is how CEO Elon Musk described the documents released for the 15-year-old Roadster. While that might be overstating it, the Roadster page includes service, parts, and owners manuals; wiring schematics; and R&D documents on the car’s battery monitor board, vehicle display system, and HVAC controller. A trove of useful information for owners of the 2,450 Roadsters sold.
