Ah! Alright. My apologies! I have to head into work, but I do want to try to answer your question.
To decompile the mod, you'll have to right click the mod in your Mod Launcher, choose the 'Decompile...' option, choose where you'd like to extract it, and then navigate to where gFamil.p3d is located
. However, Maz did a little bit of extra work on their part, and made this little meme vehicle mod it's own separate vehicle from the original Family Sedan (famil_v.p3d
So basically, you can't just drag and drop it to replace the original Family Sedan normally. You'd have to re-name the car so it has it's original skeleton name back, fix the 'suspension' skin that was added, change the car index number back to the original '4', and then re-name the P3D appropriately. Most of these steps have to be done using Lucas' P3D Editor.
Due to the simple 'meme' categorization of the mod, I assume Maz would be comfortable with the P3D being shared on it's own, so I went ahead and quickly renamed the car back and uploaded it to my personal Google Drive account. You can grab it here.
All you'd have to do is change the file name to 'famil_v.p3d
', and drop it in art/cars
As a quick footnote, I would highly advise against directly replacing the original game files if that's your intention. You can also just drop the modified famil_v in a mod directory's 'art/cars' folder and play the game with the Green Sedan immediately available to you. Yay, off-model goodness!
