The exact year, make, model, trim, operability, approximate state of charge, ground clearance, curb weight, modifications, and key or access method should be disclosed. A vehicle that powers on but cannot shift into neutral or roll as expected may need to be treated as inoperable for transport planning.
Follow the vehicle manufacturer's transport and towing guidance for that model. If the vehicle has warnings, battery damage, collision damage, fluid leakage, or a suspected high-voltage issue, disclose it immediately; ordinary auto-transport equipment may not be appropriate.
