It's probably obvious that a Mercedes-Benz S550 will be costlier to insure than a Mazda 3, since the former comes with a bigger price tag and potentially bigger repair bills. Still, pricey luxury cars aren't the only vehicles with a steep insurance expense. When setting rates, insurers consider how likely a model is to be involved in a crash, and for various reasons, some models have poorer records than others in this regard. Because of this factor, some bargain-priced cars — like the Mitsubishi Lancer or the Scion tC, for example — can be relatively expensive to insure.
