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.
