Tips and tricks of the consultants

Hello, I have cancelled the existing insurance for my two vehicles and want to change. When exploring possible alternatives, I had a consultation. When specifying the tariff characteristics, the topics “drivers under 23 years” and “garage” were also discussed. On the topic “drivers under 23” the consultant suggested that I do not specify these, should there be any damage by a driver under 23 would definitely be regulated by the insurance and only for the run In the garage, I was suggested to indicate in both contracts the tariff feature “closed garage”, although I have only one lockable garage. Here it was argued that the regular accommodation is sufficient. What do the professionals think of these tips and tricks?
