One Millionth Vega?

[Big Block 69]

In another post on this board, there was an Orange Vega in the background. This reminded me of a car I saw on a car lot several years ago. It was an Orange Vega GT with Yellow stripes. It was very nice and appeared to be all stock until you opened the hood. It had a V6 with a 4 or 5 speed. In the recessed area of the outer door handles, there was a sticker that said One Millionth Vega.
Later that week, I was in one of the area junk yards and saw another orange Vega GT with the same yellow stripes. This one was sunk in the mud and had been there for a while so I'm sure it wasn't the same one. This one also had the same stickers in the door handles claiming to be the "One Millionth Vega". This one had no engine, but the gentleman I spoke with said when they got it, it had a V6 in it.
I have never heard of these cars until this and have never seen another one.
Has anyone else ever heard of these One Millionth Vegas?
