I dislike them.
When they came out they were about the only performance-minded Japanese import available in the States and got lots of praise from the press. Since then, with the RX8, the Lancer Evolution, the WRX STi, and domestic competitors like the new GTO... they've really lost their luster.
They've also pretty ugly and pretty much ignored what made the original 240Z so great (although to be fair, the 280ZX and 300ZX did that too).
