Cognoscenti
The Cognoscenti is a luxury sedan appearing in Grand Theft Auto IV and Grand Theft Auto: Chinatown Wars. It is based on the Maybach 62 whilst the whole body, two tone paint, resembles a Maybach 62 S sedan, while the front is reminiscent of a Bentley Continental GT or Flying Spur. The vehicle is manufactured by Enus. Cognoscenti means a connoisseur or an expert in a certain field, usually fine arts.
The Cognoscenti is one of the larger cars in the game, with an exceptionally long body for a sedan. The weight and length of the car make it more of a vanity vehicle than one that can be used reliably for missions; its speed and handling are lower than other sedans found throughout the city. However, it has a powerful engine and rear wheel drive, so slides and oversteer can be achieved. Because of its size, the police will designate it as a limousine should you commit a crime while in the car.
Stevie will ask you to steal a Cognoscenti parked in Alderney City, Alderney. Two Cognocentis spawn outside Jimmy Pegorino's house: one outside of his mansion and another inside the garage.
Variant
A pearl white painted Cognoscenti can be stolen outside Gracie Ancelotti's home in Alderney City a few days after you complete the mission I'll Take Her, when she appears as a random charachter. The car will be parked in the driveway to the house, and will keep respawning until the mission is completed, so you can take it without doing the mission. Sometimes when you imput the cheat to spawn a Cognoscenti, a pearl white one will appear.
Alarm
All versions come with alarms but the ones at Pegorino's house do not trigger when the doors are opened. Like the Turismo at Mikhail Faustin's house in Beachgate, Broker, it will trigger when a window is smashed in a full speed collision.
