Adding cars into IV isnt possible yet (though i wish it was !) just hang around somthing will eventually pop up.
Can we change sounds in game say change the car sound on roman's taxi...?
From what i can see no i haven't seen anyone mod in game sound yet.

Read this tutorial its for SparkIV but should work with OpenIV too (pretty much do the same thing anyways) [TUTORIAL] Importing Textures Into SparkIV And another tutorial by Fabio206 [TUTORIAL] Importing Textures Into OpenIV also you need somthing that opens and edits PNG files eg Photoshop or GIMP.
