I know thats not what the original version of the word is. Obviously its Japanese Domestic Market. But what im saying is in today's world, people use it to describe the particular way a car is modified. I'm not saying i embrace these words but it is what our society uses. JDM, Sex Spec, VIP, Muscle etc. It's just words that people use for a descriptive purpose of a car. There are no preset rules to modify a car, therefore people like to categorise the certain ways people have modified them.
I know it can be annoying and stupid, but im sure most of us on here understand if some one says "For Sale, Sex Spec S15" or "For Sale, JDM tuned R32 GTR". Your not going to think the S15 is a drift cop with a matt black paint job and your not going to think that the R32 GTR has a set of Dolce wheels and a pink paintjob.
