Started off as a bunch of high school kids who would do late night stints in their garages making their beaters a little better. Grew into large community of JDM owners who are passionate about anything and everything JDM. I must watch!

This guy is definitely the most JDM of the lot, purely because he's Japanese :D Okay bad joke, he owns an Evo 8, 2 RX7's and a bunch of Cafe Racer bikes. He's an avid YouTuber and is consistent with his content uploads. Check out this channel for some great JDM content.

You gotta check this guy out, he's been away for a little while but is planning on making a major comeback to the platform. I believe he owns 2 x RX7 FD's, an MR2 and an R32 GT-R! He also plans to increase his JDM car collection in the very near future!
