The Stanier is based primarily on the 1992-97 Ford Crown Victoria with some influences from the 1998-2011 model. The Crown Victoria is a popular vehicle for police and taxi applications for its performance and durability due to its body-on-frame construction, rear wheel drive layout, and V8 powertrain. Unlike the Declasse Merit or the Bravado Buffalo, there is no consumer variant of this sedan, in GTA IV. However, the civilian varient was finally added in GTA V. Ford discontinued retail sales of the Crown Victoria in 2008 in the United States similar to how Ford discontinued retail sales of the Crown Victoria in Canada in 1999 while retail sales continued for the Middle East until 2011.
Regardless of its application, the Vapid Fleet Sedan features a front pushbar, CB radio equipment, and black wheels with chrome centercaps. Law enforcement models additionally have a police computer, roof-mounted lightbars, and a spotlight mounted on the driver's side. The taxi variants have a rear pushbar, fare meter, taxi lights and markers, and a hood-mounted taxi medallion; some taxis may also have roof-mounted advertising.
The commercial model, which is the basis of the Police Cruiser, Taxi, Sheriff's Cruiser and Unmarked Cruiser, has been updated for GTA V. This variant is based on the 1998-2011 model of the Crown Vic. The GTA IV model still appears as a civilian car.
The Stanier is powered by a 4.6L V8, coupled to a 5 speed gearbox in a RWD layout. Acceleration is good, and the top speed is above average and its braking and suspension are very good. It has a low rev limit, which can be felt at higher rpms. Also, the engine feels as if it runs out of steam before the transmission switches gear. It has a higher top speed than its Declasse- branded competitor (Merit).
The car's weakness lies in its poor suspension, as the car experiences incredible amounts of body roll and has a tendency to oversteer off throttle. Stability is average at high speeds, but due to its very soft suspension the car does wallow and float about quite a bit. The car does appear to have some decent tires on it, however, which does help with improving the handling quality, if only just a bit.
Crash deformation is also average, and the suspension does not take very long to start meandering one way or the other. The engine is not fragile, but is certainly not the toughest to destroy in the game, although it fares better than the "Buffalo" Police Cruiser.
- The vehicle comes in two versions. A model that features bumpers that are of the same color with the car`s body, and a model that has black bumpers.
- The LCPD laptop screen can be seen on the dashboard, hinting that Rockstar used the same interior models as they did in GTA 4
