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. However, some have managed it with the three Phantoms while the turret was mounted.

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.

The best way to get this achievement is by playing on The Ark. Get to the bit with the crashed pelican there will be a Rocket Launcher. Once you have killed off the brutes two prowlers will come your way, hopefully one of them will have 3 brutes on it. Do not fire the Rocket Launcher straight away as it will only kill the brutes but not the prowler itself and will not count towards the achievement. Try shooting it with a smaller fire arm then finish it with the Rocket Launcher that way the vehicle will be destroyed.

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.
 * Note that it may not work when doing any level with Phantoms in it.
 * 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.

Also, an untested method is to play the level:The covenant,where you start with a spartan laser. a pelican will come after you take out the AA wraith, and drop off a warthog. kill a few marines, so that they become enemies, then use the spartan laser to destroy the warthog. verification needed. This method has proved ineffective.
