I picked up three packs. Two lumps of coal per pack. The first pick shows how they were paired.

I don't keep track of variations but the last pic shows that there is a variation. The tampo's are the same but the hoses are a different color.

Now I found a Ridge Raider.

The tampo's state:
Weise
Lopez CAMS
Adlar54 Performance
Osada Road Products

At first I thought the Ridge Raider livery was the same as a standard issue and that the color was the only difference. But comparing to a standard issue, I can see that it is actually a new design too.

Many thanks for showing the pictures.

:) :D :p

Are these the MB version of Holiday cars? Also where can they be found at?

I found mine at Walmart. In the past, they have not been limited to one retailer. I don't know what the plan is this year.
