Did you look in the classifieds area...I think there was one for sale in Texas for a fraction of the original cost.

Other then the two build threads you won't find much more information out there. Only 6 cars I believe and those two are the furthest along (and the only build logs) as far as I know.
If you have questions let us know. Let me ask you first, what interest's you about the Apex? Cost, looks, something mentioned about it in the main thread?
