But statistics can be bent.
In Canada you pay more premiums for a 2 door car. 2 door covers a lot of the high power cars (toys) that have high costs linked to them. But it also covers cheap, low power commuter cars.
Statistics show that 2 door cars cost them more, true. Is that an indicator of what is actually going on? No, 2 or 4 doors has nothing to do with it.
As a result almost no one buys a cheap 2 door if a similar model is available with 4. because it will cost a lot more in the long run.
And statistics don't tell you much about an individual. I'm male, single, and have never had an accident in 32 years of driving. A close relative of about the same age is female, married, and has written off 3 cars (and a tree, a light pole, and another car) even though their so wonderful statistics say she should be a lower risk.
