Yup, insurance is a nightmare for youngsters. Our step lad is 17, his dad (don’t ask) bought him an Audi A3 as his first car.
Insurance is £1500 for the year, plus a black box. Putting him as a named driver on our car (Fiesta) whilst he was learning was relatively cheap (think it was an additional £200) but he needs his own insurance to get some no claims.
The black box is a god send tho, we can see on an App his driving which looks at speed, cornering, smoothness and even the times of day he drives it.
We just did a comparison site check for the insurance.
