Also check your car insurance policy documents, some do a new for old replacement on cars that are less than 12 months old. You can then take out gap before the car is 12 months old.
Found that out myself only this week - Quote me Happy docs state that if repair costs are 60% or more of the list price of the car (write off) or the car is stolen and not recovered and is less than 12 months old a new car of the same specification will be provided.
