Are car parts shared by other car models within a automakers lineup? In most cases the answer is yes. How exactly does that affect the automakers and why do they do it? One of the main reasons is because of the fact that it costs a lot of money to develop new car parts for a new model that a company wants to develop and sell to the public. In addition, if a automaker shares parts with other models in its lineup, it is easier to train employees how to fix the parts and makes things easier for the automaker and part suppliers in general. Also, automakers usually can improve their reputation in the mechanic world by being simple to deal with in terms of car parts and the cost that they charge for car parts. The cost of parts of course can be lower if they are shared between more models, reducing the costs overall and the ability to pass those savings on to people. Why do people and customers in general benefit by the practice that automakers often share car parts? There are a number of benefits that are obvious to the average consumer. If a person has a part that they need and it cannot be found on the model of the car that they own, then there is a good chance that it can be found on another model that may have that same part that they may need. In addition, a consumer does not have the burden of paying for more research and development costs that come along with new parts that may have needed to be developed otherwise if parts were not shared. In addition, people have more ability to work on their cars because of this practice due to the fact that parts don't change as often, allowing regular people to have a better chance to be able to work on their cars. As the global automakers have to watch their costs more in the future, it is likely to continue the practice of sharing car parts among multiple models within a automakers lineup. This will reduce overall costs for automakers, suppliers, and customers in general.
