Abbreviation for German Domestic Motors. Alike to JDM (Japanese Domestic Motors) and USDM (United States Domestic Motors). GDM implies a higher class of car manufacture and car parts. It is also a tuning style wherein Japanese cheap parts and modifications are avoided and higher quality parts and clean and subtle modifications are used. A GDM BMW can have BMW Style 32 wheels, not Koya Driftecs.
JDM owner "Hey check time attack front lip and my Advanti rims in a fluro colour!"

USDM owner "Wooo horsepower! I am driving on the wrong side of the road!"

GDM owner "Factory tuned. You're doing it right."
