All credit goes to p4elkin for the model, I just added some parts and texture.
p4elkin's Mercedes-Benz C63 AMG mod link: https://www.gta5-mods.com/vehicles/mercedes-bens-c63-amg
------------------
Things I did:
1. Added the rear spoiler
2. Added little scoops on the side of the front bumper
3. Added yellow tire branding
4. I changed the vehicles.meta to have a more accurate engine sound.
------------------
This is my first Car mod I did, edited with zModeler3. So don't expect any update's for bugs,
because I probably don't know how to fix them.
