Also helps to go for something not associated with "boy racers".
The insurance industry work out the cost of the policy by deciding how much of a risk your fella offers. I assume he has no NCB, which means that he is an unknown quantity. So that is against him to start with.
They discriminate on age and sex (although new European laws will ban the sex discrimination, and about time too - could you imagine an analogue of Diamond: "We don't insure people of one particular ethnic group as they are all rubbish drivers". Hmmmm).
They also look at where the car is likely to be parked, i.e. the home postcode. If there have been lots of car-torchings there then there will be an increased risk, hence greater premium. And what you do for a living (footballers get absolutely botty-burgled.).
Anyway, that is getting from the point.
New Astra 1.6, me at 21, with no previous insurance, no points. It cost me about £900 a year fully comp. With 2 years NCB it is now down to £445 and I shop around every year.
Something that you would imagine your mum driving is generally a good start. Something that you could imagine doing burnouts outside the cinema is a bad start!
