1979 Mazda RX-7 Limited Edition (1 of 3,000 made)

This is a very rare model of the Mazda RX-7, it is a First Series of the First Generation RX-7 and was manufactured in 1978 and sold in 1979, most people know of this model as the FB models of RX-7 however this model in particular was built before the FB and was an SA model, that’s not what makes this car rare though, it is very unheard of but in 1979 when the SA was being sold they made 3,000 Limited Edition models, I don’t know what was significant about these 3,000 models other than what’s listed in the original ad I have for the car which can be found in my pictures, or why they built these models of the SA, but It’s a very interesting car and if you have any questions about it I’d be glad to answer them and if anyone knows anything about the car I don’t I’d be glad to learn about it, thanks for reading.
