There are many things that I noticed different about the Z/28. The rear diffuser around the exhaust outlet is different, and kind of flows with the honeycomb shape of the grill. The Z/28 also seems to have separate pieces around the wheel wells on the fenders. They protrude out instead of being flush and one piece with the front panel. Overall, it looks way more aggressive, and I kind of wish I didn't have a front bowtie on mine now... LOL
