The Renault R4 mod by J3D (RENAULT 4L CUP 1.2) has no outside sound in my case. I have CM. But I don't want to replace that sound with a sound from an other car. Inside sound I have. I have latest AC version.
It's an old mod probably, so the sound file would need to be redone. You'd need to talk to the mod creator, @J3D MODDING if he can help you. The car is not for download on his page though. https://j3dmodding.com/
