I want to know who made the model of this lowrider bumpcar…

The reason i want to know is that i have recreated it (in brushwork) and used my tool to make it bumping (animated MD3)…
I want to use the new model as an example, and distribute it (source map + animated model), for my tool,
…but not without giving credit to the person who made the original model.
(btw: the image is the model i made, not the original one… but it looks the same).
The shaderfile has only 1 line of comment saying: Chronic Dr.Dre lowlow
