The Comet is a sportscar based on the Porsche 911. The Comet is all-wheel-drive like many of the newer models, yet looks most like a 911 cabriolet from 1976 or the early '80s. The front resembles a 1968 Mazda Cosmo more than a 911 though ( which might explain the name). First Featured in GTA VC, also in GTA SA.
Acceleration, speed, braking, and handling are all among the best in the game. In games prior to GTA IV, the Comet has the added advantage of being similar to a top-down convertible, which enables the player to jump into the driver's seat from the left side of the vehicle without opening the door, facilitating a more rapid take-off.
The Comet has also been spotted in a screen capture for GTA IV. It now appears in a hardtop coupe form, instead of its usual targa-top configuration. However, it retains its Porsche-like silhouette, although its design now appears to have been influenced in part by a BMW Z Coupe.
