I have no problem with mods and I can appreciate craftsmanship, but some mods move the car out of the Z realm for me. For example, a GTO bodied Z is no longer a Z. It's a GTO kit car. A Z with a SBC isn't to my taste, but it's still more of a Z than a GTO replica. Same goes for convertible Z cars. Once the roofline is changed, it's not really a Z to me. I do like regular body kits including front and rear fascias, wings, airdams, flairs, etc. I think many of those enhance the Z-ness of the car if don't right. This might wizz some people off, but to me, a bone-stock 2+2 S30 is barely a Z. They can look good with mods, but the stock ones are a huge compromise to what a Z is all about. Again, I think it's the roofline.
