A snow covered variant of the Rancher XL is used as an escape car in the mission Prologue, this variant of the car can also be stolen in Bury the Hatchet. Like other snow covered vehicles, it cannot be stored in a garage (without save editing) as they do not spawn in Los Santos.
Trevor Philips owns a red Bodhi which is readily available after and during Mr. Phillips, Mr Raspberry Jam is tucked behind the bull bar (unless the front bumper is changed at Los Santos Customs) after the completion of Hang Ten. Its license plate reads BETTY 32. It is destroyed, rendering it unobtainable if the player completes Something Sensible.
Jimmy De Santa owns a unique yellow BeeJay XL, however, it is repossessed by Franklin in Repossession, the car can be kept after the mission completion, it has a more aggressive sound than the normal Beejay XL.
A unique baby blue Landstalker can be obtained from the mission Unknowing the Truth.

The Asea can be obtained after the mission What Lies Beneath. This is the only time in the game the Asea spawns in the game (PS3/X360). To obtain it, you can fire a gun before Abigail enters the car, so she will run away scared, therefore unlocking the car and were ready to be driven.
A snow covered Asea appears in the Bury the Hatchet. This car is only obtainable by save editing.
Before the 1.16 update in GTA Online, it was also considered one of the rarest car in GTA Online, the way to obtain it is to choose the car as a starter vehicle in Mall Or Nothing.
During the Mission Nervous Ron there were 2 unique Blazers. Trevor has a unique all red Blazer with a unique license plate TPI1000 and Ron has a unique Blazer with an all blue paintjob and unique license plate B3LI3V3.
The Skylift can be obtained after the mission Sidetracked. This is the only time in the game where you can obtain the Skylift.
The player must also uninstall all of the patches and DLCs before doing this, as Rockstar Games have patched the method to obtain the Skylift. Reinstalling the patches and the DLCs will not cause the helicopter to disappear.
