Slushy? If the lines were "slushy", it sounds like you may have been very close to possibly popping the freeze plugs and maybe something worse if the block froze.
Not sure what your temps are for winter in your location, but it sounds like you are already questioning the previous owners maintenance schedule. Just for piece of mind, I would recommend you flush ALL the coolant (pull the knock sensors) from the system and flush the heater core as well.
Then top it all off with a 50/50 mix of green and Distilled water. Be sure to bleed the system afterwards and enjoy the toasy cabin that you will have along with the piece of mind that the block wont freeze. Figure 2 gallons of coolant and 2 of water for a complete flush.
PS - Good time for a new T-Stat too.
PS#2 - If the system was negleted for a while, may be a good idea to replace the restrictor valve on the heater hose and get a new plastic T fitting or consider making one out of metal.
