i never found the critters but when i first bought my z none of the stereo equip worked. well after i tore the entire interior out to replace and everything and run new wires for higher pore amps and everything... i found at least 3 pounds of shit, idk if it was field mice, chip monks or whatever but they had nested inside ever speaker enclosure all inside center console up behind the gauge cluster... i mean the owner did tell me the thing sat for a while but damn... there was 3 generations of crap in that car. i ended up removing all the fabric sound dampening cuz it was just nasty..
