Lloyd's Z06 floor mats are nice. Embroidered on them is the original (2001) Z06 logo. Lloyd's mats are a big improvement over GM's mats, also black, but nothing special to look at. Lloyd's are available in black or red for the Z06. I went with black but tempted to get red to match the modified TR interior. I think they retail for $90.
Lloyd also sells a cargo mat for the Z06. Retail price is $130.
Thanks for the website and tip Torched and HCVONE. Just checked out the site and I was extremely impressed with what I saw. Definitely going on Dad's "hints" list for Christmas! Gives me enough time to think if I want red trimmed front mats in my black interior EB.
