yeah well he was close to 6, which is only a year away from 7, and kids in yr 7 are 12, which is the new 13, which is close enough to 14, and he can get a job at15 (only 12 months away) and having a job means he can afford a car, and 16 is the same as 17, which me may as well round up to 18, so he was technically 18
