Specific Xbox 360 kiosk disc help needed

[GM80]

There were unique cars for Burnout Revenge available from retail kiosks several months ago at different retailers, the type of thing where you would download them to a memory unit for free then transfer them to your box. I know there were at least Circuit City and Best Buy cars, and I think the major game retailers had their own as well.

I WANT THESE CARS! It crosses my mind every time I see someone using one online. As a completionist, it's annoying to not have them and the specific kiosk discs have long since gone out of circulation.

I know they must be on a specific version of the Xbox 360 Experience kiosk demo disc, but I don't know which. Furthermore, I guess there must have also been a specific sub-version (such as "1.4a"?) for each retailer.

Anyone have any information on this, such as a website that lists the contents of specific Xbox 360 Experience discs?

Also, if YOU have all the cars, I would pay you to put them on a memory unit for me. I'd send one to somebody if I can't find the discs I need. I haven't been able to find that info yet, though, and I'd prefer to just buy the discs for my 360 collection anyway.
