HI Chen, Thank u for your business, help & time ! Well lets see..you paid for an Open Carrier transport. Enclosed shipping is around 60% more expensive in cost than open. You wanted best rate for your budget so you opted for open shipping. Our quote dispatched for $8 less than the original estimate. When you ship open over 350 miles its usually a 7-10 car hauler. Carriers provide estimates since they are truck drivers. You accepted our terms & conditions before pick up which clearly states this. ** Call FELICIA @ (602) 428-6872 on her direct line from 6-3pm PST or text her anytime , felicia@autoshippinggroup.com ** Auto Shipping Group is A+ Rated and Accredited with Better Business Bureau ** Military and Student Discounts Available **
