Mustang Mach 1

I just found a new car in my garage, at the same time that I was checking out the DLC.

It is 1971 Ford Mustang Mach 1.

It does not seem to appear in the DLC list from the news.

Funny enough I am using the spread-sheet from our friend Manteo Max (his old google document, just before he became mod if I remember correctly).
He had that car listed from a long time ago already, and I was wandering why, but did not dismiss and delete it.

Any one knows why this car appeared suddenly ?

Is it part of DLC, or just a VIP thing ?
Thank you

DLC from two weeks ago:

though I’m not sure how it would have popped up in your garage. You’re sure you didn’t buy it?

I wrote garage by mistake, it popped up in the shop.

I just followed your link, and found the additional list.
Thank you.
Funny enough, they are all the cars still on your old list that had not appeared in the game yet.

Must have popped up in the dealer ship.
