Well, if you just want a Pontiac calendar, I got KCPMC's done and up for sale yesterday.
I know it's still not as cool as having your own car in one, but at least it's Pontiacs.

They're at cost, there is absolutely zero profit being made from them so I am not posting this to just try and sell more.
If someone was really ambitious, you could probably still get one together in time at Cafepress. Not me though, I'm too burned out from KCPMC's.
