Thanks for the kind words folks! These pics are a bit old, but I will try to take a new set soon in good light (and after I've cleaned it a bit) to demonstrate the color better.
When I bought it, I special ordered it, mostly because I don't like to buy cars right off the lot. The dealer told me they had never seen the Z in this color before, and honestly I have never seen another in person.
I usually buy colors based on their ability to hide dirt, and the silver colors were my original choice, but this just looked interesting in the brochure, so I took a chance. For me, having previously owned two orange cars (an '00 Miata, and an '84 Bronco II) , olivine green was not as dramatic for me as it may be for others.
