I drove an '85 Z for 20 years and loved the performance and reliability so bought the new Z. I'm loving it as well. The fuel economony isn't great but I haven't had it long and have been driving "stop and go" around town so it's not a "true" picture of what highway driving fuel use would be. Some say it's a "rough" ride but I say it drives like a sports car should!
Everything's within easy reach of the driver. It really hugs the road and has a good, solid "feel" to it.
All seat adjustments should be power - some are and some aren't. I'm only 5' tall so having to adjust the height of the seat manually is somewhat inconvenient.
