I was getting those a lot a while back, phone calls/letters/emails.
Bottom Line Up Front: Used Z (in nice condition) = Good for negotiation.
Our cars turn heads, run well in the cold, and SERIOUSLY stand out in the sports car world. It makes the money-careful consumer lean a little closer.
Apparently in Fife, WA where I got my Z, sales began booming in late 2009-early 2010. When sales fell, visitors to the dealership were asked "Why not the Z?" and their response was outright "Too expensive."
I've been on email distro with the manager since I bought it. He mentioned when he took used Z cars, cleaned them up, threw some shiny 19's on them and put them out front. The sales took off faster than expected.
I figured it's a regional thing, however. The Z was gaining SERIOUS momentum in the Northwest from 2009-2010. How it rivaled the Impreza STI, and openly challenged both the Mustang and Audi TT drew in buyers (myself included) likes dogs on bacon!
