rebuild or start new ????

bought an e-maxx several months back . Planned on gmaxx
chassis and ga bulks with 1/8 diffs , then upgrade things as I
break them . Im not too hard on equipment sowas hoping to get
by for awhile . Well gmaxx is no longer , winter was tough and
lifes unexpected curves sure change plans . This thing really
needs quite a bit . So , should I rebuild or start new ? Any
info or plan of attack would be appreciated much .
