well, like i siad your the first i've ever heard saying that. my dad was a master mechanic and specialized in the z series. he barely ever saw them in the shop. and i've been talking to a bunch of adults, who grew up on these cars, all tell me they never heard of them being known for issues other then rust. hell our 280zx was in our family for 16 years and the worst thing that ever happened was the tranny needed rebuilt. we had 237 thousand miles when we sold that thing and it still ran the same it did. drove it to disney god. litterly hundreds of times. never towed once.
