*THIS MOD DOES NOT ADD ANYTHING TO THE GAME, IT JUST USES THE VANILLA SOUNDS ON DIFFERENT CARS* 

I never liked how Rockstar managed car sounds in this game, they used lots of diesel engine sounds for cars that just don't have a diesel option in real life, especially in the U.S. where the great majority of cars are petrol powered. 
I've changed the sound of quite some cars, especially SUVs, I don't have a full list but I'm sure you'll notice the difference (Maybe I'll make one in the future) 

- Installation is easy and much faster than before. 
- No need to add new sound files, installation is just one file 
- Changed more car sounds and tweaked existing ones 
- Now pretty much every car sounds as it should 

Known "issue" 

- Police sedans have the FBI siren sound 
- Police calls out some modifed sedans as "SUVs" 

V2.5 changelog 

- Used sounds from DLC cars such as the Windsor and the new Schafter
