Now that's JDM tight

[x_o_k_x]

pure JDM cars would be something imported from Japan with RHD.
JDM cars could be anything that was built in Japan and being modded to JDM style/parts.

JDM= 1) for some, it means CHEAP mods to their car (painting their hood and rims black, or installing cheap black plastic front lips on Honda/Acuras, etc) to give it a "JDM" look (Japanese Tuner Look) which is so totally wrong. Oh, and buying Rota wheels. They are made in the Philippines, and not Japan, and are knockoffs of REAL JDM wheels (Volk, 5zigen, Mugen, etc.)

2) For the real JDM fanatics, it means importing "high end" tuning parts that cost an arm-and-a-leg to ship over, and that are also very rare.

1) is usually when we say JDM as a joke
2) thats more like it lol, especially now when yen worth 50% more then 12 months ago
