prop_vehicle_jeep is a point entity available in Half-Life 2 Half-Life 2, Half-Life 2: Episode One Half-Life 2: Episode One, Half-Life 2: Episode Two Half-Life 2: Episode Two, and Half-Life 2: Deathmatch Half-Life 2: Deathmatch. It is a drivable vehicle with the ability to have a mounted Tau Cannon.

models/buggy.mdl, the Half-Life 2 jeep model
models/vehicle.mdl, the Episode Two jalopy model

Half-Life 2: Episode Two Half-Life 2: Episode Two gives the vehicle some additional functionality, including blinking hazard lights, a radar that detects specific targets, a holder for Magnusson devices, and various additional inputs.

Warning.pngWarning:It must be given a model, otherwise the game will crash when loading the map.
Tip.pngTip: In Episode Two, info_target_vehicle_transition entities can be used to create points that the car is teleported to during a map transition, in case the player leaves it behind.
Note.pngNote:This entity is unimplemented in Half-Life 2: Deathmatch Half-Life 2: Deathmatch .
Note.pngNote:It's possible to use the original buggy model and script in Episode Two, and the Tau Cannon is even still functional if enabled. However, the added hazard lights become misplaced below the car as the original model is missing attachments for them. A modified model could be used to move them to a reasonable position, but the code would need to be modified to remove them entirely like in HL2.
Todo: What exactly needs to be changed?
Note.pngNote:The Episode Two car is also used in Portal Portal , but the resources aren't included by default. Additionally, the radar causes a crash due to an unregistered user message.
