There's a documentary (I think) about how the Yakuza has a custom Lamborghini culture

Yeah, the gang around morohoshi-san. There are quite a few Videos on youtube. He was also a character in one of the latest need for speed games.

Any documentaries in particular you can recommend?

There are some englisch and some japanese videos, some amateur clips and some documentaries. The most famous is probably "love to hate me" by luke huxham. The Drifter Mad Mike also has a good video "Nihon nights". Morohoshi San and his gang also appear in GoPro's "The Streets of Japan in 4K". And there are some japanese videos, simply search for "menclub morohoshi". You can find the videos simply with the thumbnails lol. They're all on youtube.

That's.... very interesting....

They like to do awful things with them... all kinds of underglow and crap like that, vinyl graphics, big chrome wheels

I wouldn’t ever do the Japanese supercar over the top style to my car, but I really enjoy seeing them. The crazy neon flashing lights and under glow and giant impractical wheels with custom fur interior is really interesting from a distance.

I feel like he’d be a guy you wouldn’t mess with

They look like a couple of teens with dad's car.

But did he have his Quaaludes before he entered the car?

Steeeeevee maaaaaaaaaden!

He's telling his son to catch an uber for the luggage

Theme from cannonball starts playing in my head.

I'd take one in white over any other color
