You can change your shipping dates anytime. The only exception is when the driver is already on the way to pick up the car. Until then simply contact your shipping agent via call, text or email and ask to change the date for a new one. Please note, that if you want to ship your car earlier than planned, there may be a delay since the drivers for earlier dates may be fully booked. Nevertheless, we will do our best to suit your needs and ship the car within your time frame.
