Some companies will have this on your policy anyway, my sister was 18 and had just passed her test when she insured her car, fully comp with that as a benefit of the policy was still cheaper than my insurance as a 22 year old guy, 4 years ncb and not being allowed to drive other vehicles because im under 25! If i go with Quinn i could get that benefit but i'd be paying double what i pay elsewhere. Some companies if you phoned them up and explained the situation should allow you to insure the car as its a family member who owns it, a friend of mine insures his car himself however his dad went and did the sale and put his details on the V5C by accident yet the cars insured by his son direct. I also insured the car registered to my sister for a month or 2 before she passed her test as my car was off the road, i did so with chris knott. Its all down to the insurance companies how they'll deal with it and what benefits you get.
