The Z is just plain impractical...
...that's why I have a CRV (just picked up a used '08 last night)
I love the Z for the pureness, and I don't have to pay for all the factory bells and whistles since I rather get something better from the aftermarket. For example, the Z's base head unit is easy to replace without the need for special hardware. I don't have to worry about the crazy integration. The HVAC panel, while not as fancy, is super easy to use so I can focus more on driving. Such simple things minimize driver distraction so more time is spent enjoying the car.
