For sale: 1x Halo 3 Mongoose. One previous owner, excellent condition. 4WD, air conditioning, jungle camouflage. No battle damage, full service history. $9000 ono.
The Mongoose is actually a modified Kawasaki ATV, and was used rather publicly during the big Halo 3 launch event in New York City a few years back. Should still be in good shape if the seller's appraisal checks out, but Halo 3 purists please note: no mention is made of whether you can actually snuggle two adults together on the thing or not.
