I understand that the 100 hr minimum hrs applies at ADP before taking away a Seneca solo without a free CFI as safety pilot (all the CFI's want to ride shotgun for free just to make up their own twin time!) the exception is when the renter has an ME Inst. + 25hrs. It's only the Seneca 1's that ADP rent out as takeaways I believe though. Not sure if anybody will rent out any twin to a low hours pilot!
