I give up. There appears to be neither rhyme nor reason to motoring insurance premiums. The insurance groups given from searching
http://www.abi.org.uk/carinsurance/ don't help because the premiums that insurance companies charge don't reconcile with the groups. It irks me that profit-driven entities have more power than the police to determine who can legally drive what -- hence this rant.
The catalyst for this is that my son has outgrown his first car and we're looking for a replacement. I got caught by the insurance companies when we bought his first car. We had a quote initially for a Renault Clio (group 4) that was affordable. We bought him a Citroen AX (group 2) and (after we'd committed to the purchase) were horrified to find that the premium was nearly double that quoted for the (higher insurance group) Clio. Needless to say, this time we intend making a nuisance of ourselves by asking for a quote for every car we consider.
My son want's something a little bigger and frugal. So, we've been looking at "sensible" cars and have test-driven a Peugeot 406 and a Rover 420 (both turbo-diesels). For the 406 (group 10) they wanted nearly £200 extra premium and for the Rover (group 11) they wanted nearly £160 extra. My wife has a 140hp, 2.5 litre, Volvo 850. This is a group 13 car with significantly more performance than the cars we've looked at for my son. Just for a laugh, I asked for a quote for the Volvo and was astonished that they only wanted £99 extra premium.
It just doesn't make sense. I had thought that the premium charged depended on a "driver risk" value and the insurance group; the quote would be obtained from the intersection of these two values in a simple table -- but no! Here, "driver factors" are identical but the premiums charged bear no resemblance to the insurance groups. There is also evidence that insurance companies "change their minds" about certain cars and change the loading from year to year. A classic example is the huge premium hikes that afflicted hot hatches in the seventies. So, a youngster could get a car with reasonable insurance costs only to have the companies change their mind enough to make the car non-viable at renewal time. For a very young driver, the insurance costs are likely to be bigger than all other costs combined. So, it is surely unacceptable that such uncertainty exists.
FWIW, I can now understand (but not condone) why some motorists drive without insurance and think that it's high time the insurance companies were brought to heel.
More pragmatically, does anyone know where to get a reliable "ball-park" idea of premiums without having to ring around the insurance companies for a quote for each likely car?
