After I've finished the main story and all S&F missions, I decided to go on the hunt for some rare vehicles. I just wanted to see what kind of rare vehicles you guys picked up and maybe you can give me ideas to search for cars I don't have. Here are a few cars that I have found in the last week:
Rusty Rebel 4x4 (Trophy Truck Mods)
The Rat Loader
Batti 801 R.R (Sprunk)
There will probably be more cars to find on GTA Online, so I might get more.
