I am using the shipping tie down points on the car. There are two attachment points on the front half of the car that you can put a tow hook through and secure the front. For the rears, I use the little slotted holes by the rear jacking points and special hooks that I got from northern tool that fit in and rotate, and have an eye on them to attach the hook on my strap.
I can only find this picture
but it is the hook on the bottom that fits up into that slot.
