Sometimes, you may not even notice and someone else may have to tell you that your car’s hub cap is scrapped. To replace one, you have to necessarily purchase a set of 4. Although hub caps may be freely available for a second hand purchase in the market, it is wise not to prefer the hub caps that were already mounted on a car. Be it BMW, Hyundai, Mitsubishi, Suzuki, Toyota, Scion, Volvo, Corolla or Volkswagen, you can find ideal hub caps for all make and models in the market. The average cost of hub caps is $150 to $200.
