Im 25, with 7years ncb, and I am paying £600 full comp on the Cup.
When I had my first car with no no claims bonus at all, I paid £1500 tpft on an £800 car... which was a bit pants.
Then sense came over me and I bought a 1.2 with a years free insurance.
Something people who havent bought such a car do not know is that they give you bonus years on the no claims if you make no claims in your year of free insurance... making it very worthwhile.
Now, finally I can afford a sports car, and afford to insure it.
If you are utterly convinced you want to go for the Cup, I would imagine you will be paying MINIMUM of £1500 insurance.
Im with Renault. Found Elephant competitive.
