I'm looking to get back into a Z. I have a 2011 Evo X with 6050 miles on it I am thinking about trading or selling. Have you considered an Evo X? Absolutely a blast to drive, but I miss my Z.
Mod-wise, I've got a test pipe, catback, accessport, and a few other tasteful mods. The color is rally red. Model is GSR equipped with Sight and Sound package.
Originally purchased for $36,200. About $2-3k worth of mods installed at this point. Can let go with or without mods. LMK if you're interested...
