Hello,
Sorry for the late response. In order to address this, I would need the full last 8 digits of the VIN. She may have meant a pilot vehicle is likely one that was used by the dealership for its employees to test drive. They would have driven under normal road conditions, speeds, etc. Any warranty should not be affected. Please send the VIN# if you any other concerns or questions. I hope you're able to get some road trips in with your Sky to enjoy the fall colors. Have a great week!
