It is, by some margin, one of the most popular mods ever invented as a GTA IV car pack.
The difference is that the realistic pack replaces most of the sportscars as well, including a few bikes, in addition to adding entirely new vehicles. Like the Ultimate Vehicle Pack highlighted above, the Realistic Car Pack comes with several different car mods all wrapped in one single file. It’s got a very high rating of 8 stars out of 10, and it’s been downloaded on GTA Gaming’s website over 43,000 times.
