Well he has no feedback and don't sound like he has a clue about nitro.I would be patient and wait till someone with a good rep sells one that way you know what your getting.From the sound of the add and his replys sounds like you might be getting someone elses junk and you don't want that.Look on here and keep a eye out on the bay there on there from time to time cheap.I just bought a practically new mt2 off the bay last week for 100 shipped so they are out there.If you get this truck and you have motor issues I would trade you a motor.I have a bunch of small blocks if you really need one.Good luck and honestly I would pass on that truck unless he comes down in price.I have a few 10th scale rollers I would part with if interested pm me.
