Second car

Hello! I have the following problem. I would like to register a car as a second car for my daughter (23 years old). My wife was with the LVM today, where our first car is also insured. The good woman at the LVM said: We had only two other insurances with the LVM apart from the car insurance (liability and home advice) and we would have to take out at least one insurance (e.g. legal protection) to insure the second car in the SF class 2, i.e. 85%. Otherwise we would have to Is that all right? What do you think about it? I would be very interested in your opinion about it.
