Just got a text that my car is ready for home delivery next week. There is no option to get it delivered to a Service Center near by. I am in SoCal and I know there's quite a few. So my question is, when they drop off the car, does the delivery guy wait for you while you check the car inside and out? What if something was wrong with the car and I want to reject it? Also, when do I need to pay my down payment? Is it prior to the delivery date or the day of?
