I use a Yakima Hold UP hitch rack for most cycling duties. I also have a roof rack on my Kia Soul and I scored two Thule wheel on roof top racks for cheap that I use one of them as a third option when both my wife and son come along for a ride.

I also have a Saris Bones rack that I still keep because it comes in handy when I need to phone home for support. I have had to make the call of shame twice and it's easy to tell my wife or oldest son to just throw the rack in the car and I will put it on when they arrive. The Saris Bones racks are always on CL for cheap.
