Vehicles are an important part of GTA Online, especially in RP. In this article, we are going to list out the top 5 rarest vehicles in GTA Online that almost no one has. Everyone can buy an Oppressor MK2 to grief, but not many people can get their hands on the below vehicles.

5 - FIB Buffalo

The unique FIB Buffalo is a special vehicle that the Federal Investigation Bureau (FIB) agents use. They can only be encountered at the highest wanted levels. While you can steal one after taking down a FIB agent, that specific car can't be modified or insured.

To get a permanent FIB Buffalo for keep, you need to grind out Hostile Takeover VIP missions. The one that has an obtainable FIB Buffalo involves the Los Santos National Airport - it should spawn in one of the hangars.

4 - Modded Dubsta 2

The Dubsta 2, especially the modded variant, is the white whale of GTA Online. It is an extremely rare spawn and you need to meet a number of specific requirements for it to appear. The spawn rate of this vehicle is exceedingly low - you might have to waste a lot of time waiting.

The Modded Dubsta 2 spawns between 8 AM and 3 PM near a particular driveway in Vinewood Hills. This is the best possible location for this car to spawn. It is more likely to appear in the latter half of this period, from 12 AM to 3 PM. After carjacking the Dubstar, you can just take it to Los Santos Customs to make it your own. You need a lot of luck to get the rarest vehicles in GTA Online.

3 - Space Docker

The Space Docker is a highly modified variant of the Dune Buggy with many "spaceship parts" added to its body. It is customized in an alien/space theme, with two thrusters on the back and two small wings. You can even glide for a short distance after driving down from the higher ground.

It is not easy to get the Space Docker in GTA Online, however... as it is tied to one of the older multiplayer modes in the game, Arena War. You need to grind this mode to Sponsorship tier 500 to get the Space Docker, and lobbies for Arena Wars are rare nowadays.

2 - Rusted Tractor

This is the absolute worst vehicle in the game but is also one of the rarest. The old farm vehicle has nowhere near the performance of the worst car... however, it should be the center of people's attention if you drive it around in GTA Online.

The requirements for getting the Rusted Tractor is double that of the Space Docker - you need tier 1000 Sponsorship in the multiplayer Arena War mode. This is impossible to do in 2021 unless you use bots.

1 - Lost Slamvan

The Lost Slamvan is a unique variant of the Vapid Slamvan. It can only be acquired by spinning the Lucky Wheel at Diamond Casino & Resort. You can spin the wheel once per day, and every time, you have a ~14.3% chance of winning a mystery vehicle.

However, there is yet another layer of RNG. If you win, there is only a ~0.72% chance the vehicle is a Lost Slamvan. In total, the chance comes out to a roughly 0.005% shot, which equates to 1 in 20,000. This makes the Lost Slamvan the hardest to get vehicle in GTA Online.
