Short for Japanese Domestic Market, particularly in reference to models of cars produced and sold solely for Japanese consumers. These vehicles often have features and/ or engines not available in other markets. As a result these models are often the envy of car enthusiasts in other countries.
Why does my Silvia have a crappy CA18 engine when the JDM models get the SR20DET?!
Just coppped these JDM Civic tail lights sent direct from Japan!
