HI,
I rented a flatbed locally, drove to Chicago, put car on flatbed and drove back. Flatbed rental was $75 for a weekend, rented a truck from National($240). No problems.
I was told that you needed a temp permit for each state that you drive through, border patrol in Sarina confirmed this for me.
I would do it again for my next car, you'll save a lot of money(depending on exchange rate and the car)
Found mine at a dealership, which to my surprise had great service
