My mom used to drive an 87 300zx, and I drove it frequently through high school (she still blames me for burning out the clutch
. ). It was an overweight pig. It pulled halfway decently in first gear, but after that it was terrible. It didn't handle very well due to the weight, though I was much less experienced in proper-handling sports cars then than I am now, so my memory might not be great. The digital dashboard was awful - it looked cheesy even when it was new. The t-bar roof was a pain - we rarely took the panels off. I remember the backseat being pretty small, even when I was 12 or 13 and a skinny toothpick. Basically, I really disliked it, and would never consider buying one now.
It did have a nice notch-y shifter, I'll give it that.
