Where you keep your car is important too
Where you keep your car is important too - if you have a secure parking area, preferably one that keeps your vehicle out of sight and under cover, then your risk is lowered, as will be your premiums. Cars that are regularly parked at the roadside are at a higher risk of being stolen or involved in collisions, and so will be more expensive to insure.
One final point to cover is that of how attractive your car is to thieves, and not just in the obvious way of how desirable your vehicle is! An expensive car with a good security system including an alarm and window etching etcetera will be more of a hassle for criminals to profit from, and so is less likely to be stolen than a cheaper car with little or no security. Also, a car featuring plenty of gadgets such as an expensive audio system or satellite navigation will attract greater interest from potential thieves.
So as we can see, even though car insurance is an expensive business, it's not always as simple as it seems, and by looking at what insurers want in a 'perfect' customer, you may be able to drive down your premiums.
