JDM in the car culture is something that car enthusiasts are very interested with. JDM style came from the japanese who costumizes their cars without limitations even their wildest imaginations can achieve. Japanese culture in modifying cars is very respected worldwide. In fact, even non asian countries prefer JDM style of tuning to their cars. JDM really stands out in the car culture. Because of its popularity, car enthusiasts are very obsessed of owning/buying parts that are coming from Japan. JDM for me is something that you would want to do with your car that it would stand out from the rest. " I put it their because it is needed", I think that is what JDM really means. JDM lifestyle.
