LEO's vehicles are always better than civil versions of same ones.[/size]
Did some research, this isn't the case with the civilian Buffalo.
The Buffalo's raw performance in TBOGT is considerably good for a four-door sedan, courtesy of its high displacement supercharged V8 engine, and may even be superior to its law enforcement variants. As expected, the car is capable of good acceleration and a decent top speed of 199 mph (320 km/h), but is also lighter than the law enforcement Buffalo's, allowing the car to corner and brake better.
oh, and apologies for bumping this...
