850 Wednesday!

Hi everybody!

Today I have a fleet of BMW 850s to show you! They are from matchbox and hot wheels! I totally forgot to add my mistro BMW 850 :(. One of the hot wheels 850 has open door action and I am wondering if it one of the corgi casting that hot wheels took over? The matchbox ones both have opening doors!

The two Matchbox:

The hotwheels:

All of them being friends:

Matchbox with open doors:

This is the hotwheels one with opening doors:

Dat ass:

This is the hotwheels 850 that I would like to know more info about: If it is a corgi casting how does one know this by looking at the casting? Why would hot wheels make a new casting of a car they already had but with opening doors?
