Most of the Cars from GTA IV for SA. Just copy files to your directory and gta3.img. Make Backups just incase!
Also get HQLM as some cars are compatible! (Optional)
-No bugs known, if you find any please report them!
I may Add Bikes, Planes and the Train if I find time.
Read the Readme for installation method.
I will add screenshots and the links ASAP, just submitted a ticket for larger file upload.
Sorry for the low lighting in some of the screens!
