Yes, it's the age of the vehicle working against it. It is not the safest of cars in an accident, which means should your son have passengers they are more likely to sustain personal injuries. Look for a policy that has a black box and also has a curfew on passengers over a certain time at night. Put yourself and your wife on the policy, even if you are never going to drive it, it will reduce it dramatically because it splits the risk. Try www.wearemarmalade.co.uk/young-driver-insurance or www.onlyyoungdrivers.co.uk/ or www.4youngdrivers.co.uk/. I cannot recommend any of these personally, but it is on these lines you need to be looking. DO NOT use price comparison sites, they WILL NOT want to insure you. Contact insurers and insurance brokers directly. Look for independent brokers as there are a lot out there pretending to be, but linked or owned by an insurer.
