My mod add new motor sound for all vehicles (except Vortex and Caddy). They are the sounds of similar vehicles in other games, so this is not a "best real sound". Excepted a lot of other "new sound for all cars", mine respect the original car whose the sound is remplaced. For exemple, the Voodoo is an old car. In the other mods, it has a sound of a sports car, but in mine, it has the sound of an old car.
Why I have post my mod without to be finished? Simply because your comments can help me for ameliorate my mod before I host it (for exemple if a sound is too long, too short, too strange... ). Just see this vid. But please, do not rate this mod before it was released (I know that somebodies hate the mods posted before to be finish). Thanks.

Any car as the same sound than an other (except these whose share their sound with another)
