Insurance

Hello, I'm getting a 355 this weekend and I of course needed insurance. I called the company who insures my cars, which directed me to another company to insure the car. We agreed to terms, but then I mentioned that I have to teen drivers and they said that my kids could not be insured. I want my kids to drive the car a little, at least. What insurance companies do you use, and do you have any teen drivers? Thanks for the help, I need it fast as I want to be able to drive this weekend.
