According to TFW2005, from a JP website, the MP4 Convoy with Trailer set is being re-released by TakaraTomy in October. So anyone who missed out from the first release a few years back, or the release in Target here late last year, this will be another chance to get one at first-hand prices (it'll still be expensive though, it's a huge set).
