Michael,
your response was so good, if I was an administrator I would make it a sticky for all the young 'uns who think the Z is the end-all.
For me, Jmortensen said it, "They are getting old". However, I did my first hybridZ in 1978! Yeah, most of you, check your birth certificates While there were years in that span since when I did not own a Z, I also had cars that made the Z comparable to an oxcart, but I still love the Z. There just comes a point in time when you want to do something else with another car better than the Z. Yes folks, there are cars out there better than a Z-car, especially when those cars are also hybrids.
Yeah, I know, sacrilige and I probably should be banned :D
