Boy, we've seen a lot of real-life custom Halo vehicles lately. First there was a tiny, completely huggable Warthog, then a full-size Warthog and now we've got a working, custom Mongoose. The vehicle was spotted on Craigslist and, according to the seller, it was originally used as part of a Halo 3 launch event. A modified 2007 Kawasaki KFX 700 ATV, the seller claims it was won in a drawing, but now he has to sell it. If you could use a "mint condition" Mongoose -- and have $9000 laying around -- this baby can be all yours. Once you pick it up, all you'll need is a buddy and a (Nerf) rocket launcher and you've got instant good times. [Via HBO]
