Cars that are statistically in the fewest accidents, and cars that are least-frequently stolen are the cheapest to insure. Four-door models tend to be cheaper to insure than two-doors or sports cars. Cars that have anti-theft devices installed (such as Lojack) can qualify for insurance discounts. You can make yourself cheaper to insure by taking driving safety courses. The exact cost of insurance is going to depend upon where you are located, where and how you drive, and what sort of coverage you want. You can save some money with higher deductibles and by eliminating things like towing insurance. Your state may even allow you to just have liability insurance, or even no insurance at all (which would be idiotic, but it is a choice in some states). If you are trying to create a list of cars to shop for based upon the cost of insuring them, you could simply call a few insurance agents, and ask them for a short list of reccomendations. They will ask you some personal questions to put you in a bracket, then give you some choices. You could also make their lives easier if you tell them which cars you are considering, or if you give them an idea of the maximum you are willing to pay for insurance. Obviously, shop around and get some quotes. Often the worst deal on insurance is at the car dealership. Be very careful. Insurance isn't just the price you pay, it is the service you get when you need it. Read the fine print very carefully before you sign. Consider looking at Remar Sutton's book "Don't Get Taken Every Time".

Actually, one of the biggest factors of a car being expensive or cheap to insure is the cost and availabilty of body parts in the event the car requires repairs as the result of a claim. Another big one is the vehicle's ability to take a hit. It's usually cheaper to fix a car than total one from the insurance company standpoint. One interesting example I ran across when I worked in the insurance industry was that a Mitsubishi Montero and a Mercedes Benz sedan (same model year) were merely a few dollars apart for the cost of collision and comprehensive. One would not expect that, but the Mitsubishi parts for that model were unusually expensive. The difference in the price of the vehicles was like night and day, but the insurance on the Mitsubishi was more expensive. Another example is my ex-husband's 1991 Toyota MR2 was far less expensive to insure than my 1993 Volvo 940. Both cars were turbos, mine was more crashworthy and not a sportscar, but again. . . .the cost of the parts was a factor. Just adding to other answers and offering a different perspective.

Buick Centry's are soo cheap. Its all old people behind those wheels.
