I just wanted to let people know how GREAT these buggies are. I've got the mbx-4 xr, and I am very impressed with it, its a bulletproof buggy. I just want to let people know that these buggies are great and to consider one if your looking for a new buggy. I am just so impressed with this thing, i mean i've jumped it into i-beams, carthweeled it on the straight, and colided with other buggies and still nothing has broken. The only problem I had was that the setscrew on the front cvd came loose, which sidelined me for a whole 5 minutes. I collided with a kyosho midair, and the kyosho broke, but not mine. Just wanted to put in my opinion, since theres always people asking which buggy is best, and what should i get. If your looking for a new buggy, definitely consider mugen.
