I think that the nose panel mods are just about the worst thing a person could do to a Z from a styling standpoint. I know I'm not 100% alone in this as my girlfriend laughs out loud at the "nasty nose holes" when she sees those panels (and thereafter refers to the car as "ruined"), but I will never like any of the slotted or modified nose panels. I've tried to like them ... I've worked on it, but they are just gross. So, my personal opinion is to avoid them. :) Don't take my advice though if you like them ... make your car whatever you want. Pricewise - I would check ebay or search a bit with google. I'm sure there's a dozen or more companies that make nose panels identical to Stillen's.
