Oh nothing wrong, I forgot for a moment that these are wrong number series 🙂
Thanks a ton for your post. I would like to comment that the price of car insurance will vary from one plan to another, mainly because there are so many different issues which contribute to the overall cost. By way of example, the make and model of the auto will have a large bearing on the cost. A reliable old family automobile will have a less expensive premium over a flashy expensive car.
