Tough luck young 'un. As Roland says, get someone old on your policy and the price comes down.
Even so, Chris (22) was quoted £750 for his Polo at Redditch with 1 year NCD, Caryn (18) was quoted a similar amount for a Rover 25 at Pontypridd with no NCD (coming down a hundred or so using here as the home address) and Peter would have been over £1000 on our Polo when he turns 17 in October. I tried Admiral multicar on 4 cars and it came in at £130 for the 406, £125 for the Polo (without Peter) £190 for the Golf and £360 for the Rover and they allow you to declare a driver 'at college and living away during term time' which brought the Rover premium down from living in SheepShaggerLand.
Adding the Elan brought the prices of the other four cars down so much that the Elan was effectively going to cost 5p to insure!
They also allow you to declare 'working away/on contract during the week' so we put Chris's Polo on it and got his premium down to £450 - total of £1250 for 5 cars. The premiums are taken pro rata from when the old ones run out and each major driver earns their own NCD - they also add a year to the NCD at the end of the first year even if the policy was only active for a month. Although they can't guarantee the extra premium when Peter is added, it would only have been £450 when I took it out
Some of the points I picked up were:
Living in Gloucestershire and being old has its advantages
Garaging sometimes increases the cost
Two experienced drivers can sometime go from £250 excess to £0 excess at no cost - not true for young 'uns!
The longer you've owned the car the better
NCD is very significant when adding a learner driver
Removing a driver from policy can increase premium
Adding protected NCD doesn't necessarily increase the premium
Commuting and occasional business use only add a few Pounds
Adding one driver to a car doesn't necessarily increase that car's premium but may decrease another car's premium that they are named on
Don't live near Manchester and don't drive a truck for a living!Sorry it doesn't help you much Silver, but it may be useful for those with kids at University.
