Scorpion
While this Sunrise only holds a small 2L engine, this gives it the space to hold not one but TWO RL in the front, with a Small Rocket on each side. This allows it to quite quickly decimate even the thickest of armor, and flip even the heaviest of vehicles. It does have the weakness of carrying no reloads, so when it's used its 10-shot clip, only the Small Rockets remain. This vehicle should either be kept at a distance, so it wastes its ammo, or immediately disabled. I myself have lost a fair number of vehicles and gangers to this car.
Fairly common in the larger Somerset area, and used by most gangs.
