Used Car Salesman

Used Car Salesman is a Halo 3 Achievement. It is awarded for destroying a vehicle with three enemies in it in either a ranked online playlist or in campaign. Unlocking this Achievement gives you the Scout Helmet for Spartan Armor customization. There is also a campaign glitch where you destroy a Phantom's turret with a machine gun turret (Otherwise known as the AIE-486H Heavy Machine Gun) or plasma grenade to gain the achievement. With using the Machine Gun it can not be mounted, you must be holding it.

It is represented by a yellow eight-pointed star on top of a red eight-pointed star. On top of this are three white stars.

Note

 * The vehicle has to be completely destroyed with all the people in it. Ex. If you shoot a rocket at a Prowler and kill all of the people contained in the vehicle and it is still functional, then you will not obtain the achievement.
 * One way to gain the achievement is to simply destroy the forward/front turret on the Phantom.
 * Note that when you stick the turret or kill it with the machine gun, it must be right before the enemies are being released. You'll see a purple glow coming from underneath.
 * An easy way to get this achievement is to play through the Covenant level until after the third tower has been disabled. You will get the Scorpion tank. You can shoot the Prowler that comes around the corner of the valley with the turret. If you aimed correctly, the shell should destroy the Prowler and all of the people in it.
