'67 Vapid Dominator Buggy
A 1967 muscle car cut down into an off-road buggy, stored at Paradise Garage in Watson Bay with a weapon locker and a stash box.

A 1967 Vapid Dominator stripped to a frame and rebuilt as an off-roader: roll cage, roof-mounted lamp bar, cut arches and knobbly tyres over a body that started life as a muscle car.
Rockstar stores it at Paradise Garage in Watson Bay, and it comes with a weapon locker and stash box attached.
The storage is the actual feature
That last detail matters more than the car does. Grand Theft Auto 6 moves larger weapons off your body and into your vehicle, which turns the car into part of your loadout. A bonus vehicle that ships with a dedicated weapon locker is not a cosmetic reward, it is a functional one.
It also confirms that at least some vehicles carry storage as a property rather than every car being an identical container.

Vapid and the Dominator
Vapid is Rockstar's Ford. The Dominator has been its Mustang since Grand Theft Auto IV, and a 1967 Dominator is squarely the first-generation fastback everyone pictures.
Turning that specific car into a mud buggy is a genuinely Floridian idea. Cutting up a valuable classic to drive it through a swamp is the sort of thing that happens where land is wet, space is cheap and nobody is precious about a car.

Where it will be worth having
Grassrivers and the wetland tracks, and the back country around Ambrosia and Mount Kalaga. On Ocean Drive it will be a liability.
What is not known
How much the weapon locker holds, whether stash boxes appear on other vehicles, and whether a standard Dominator appears in the base game have not been detailed.
