Rates or costs are determined by the type of insurance you want or need to purchase. For instance, if you want, or if your Lien Holder (who you make auto loan payments) wants you to have physical damage on your car, like theft and collision, then the rate is determined by the value of your car. Most if not all Mexican Tourist auto policies are written on what is called a ACV, or Actual Cash Value basis, and not a Stated Amount policy, where you can just name what ever value you think your car is worth, and then think that the insurance company is just going to fork over that amount…good luck.
