My 16yr old son got his license today, We gave him a Durango to drive, called my insurance company to add him and they want to DOUBLE the amount our policy costs. At first they wanted to assign him to my Wife's new RX350.... We told them he is driving the 99 Durango !!!! So they now want to add him as the designated driver to my truck, my 08 vette and his durango. I am like he can't drive three cars at once!... Doesn't matter to them. Since the truck and the Vette are "spare" cars they assign them to the highest risk driver for the most premium available.
