Here's a thread containing production dates of the various promo Cars...

Faux Wheel Drive:

1168
1278
1308

Sidewall Shine:
1418


N2O Cola:
2128


Gask-Its:
0589
0619

Blu-ray McQueen:

These are the dates of the ones that I have that are opened... I have more of the N2O Cola and Sidewall Shine promo Cars but they are in sealed baggies in the TRU display cases with solid black bottoms.

If you have any promo Cars with other dates, please post in this thread and I'll update the list.

Many thanks.
