I ran across this car the other day: The text is absolutely useless—a list of the Z8's generic attributes, nothing at all specific to this car (AH61390). No mention of the Dinan mods—however, this car is sitting on Dinan wheels (produced specifically for the Z8) and has D I N A N splashed across the deck, and you can see the Brembo brakes over perforated discs. I am betting it has the full Dinan suspension (NLA), and perhaps even the beautiful exhaust headers that so riled the Z8 purists.
I see Dinan air boxes but no strut-tower brace, and of course there is no mention of the hard top. Still, if this is a full-on Dinan Z8 in Jet Black over the black-and-créma interior, I think it's a bargain with under 20,000 miles at $170,000.
UPDATE: They're not Dinan wheels, they're HREs. Here's the car on the dealer's website. Yes, the hard top is included.
