If you ever see a Ferrari or a Porsche motoring down the road, chances are the owner is paying out the you-know-what for auto insurance coverage. That's because such high-profile cars are more expensive to repair and popular with thieves. Think about it for a second: When you were a teenager, what was your first car? My cousin had a 1976 Cutlass, which was cheaper to insure than my brand-new Mustang. So, if you want to save some dough, forget the Ferrari and buy a Taurus. Also, before buying a new car, research the cost of insuring the vehicle.
