The cost of certain parts of a vehicle can be as much as a third less than the price of a similar item from the same manufacturer, according to a new study.
Car parts are made from a variety of materials including steel, aluminum, carbon, plastic and metal.
The study from the Massachusetts Institute of Technology looked at the costs of parts produced by different companies in the United States.
It found that the cost of a replacement brake wheel at Toyota’s plant in Michigan was about a third of the price at GM’s plant, for example.
The study looked at two major U.S. automakers, General Motors and Toyota.
The cost estimates are for the parts produced in the two companies and do not include parts produced for other companies, the authors said.
The researchers looked at what part a particular vehicle might need for repairs and the cost that would likely be required to make that part.
The costs are not adjusted for the price that the manufacturer or dealer might charge for the same part.
The cost of an average tire was calculated to be about $2.75 per tire, the researchers said.
