Jerry Seinfeld cheated death, but what the hell is a 1967 Fiat BTM?

We all know of the latest news that Jerry Seinfeld cheated death in his 1967 Fiat BTM which Peter reported yesterday (See Here), but what the hell is a 1967 Fiat BTM?

To me personally and probably me being stupid have never heard of a 1967 FIAT BTM, I have heard of a Fiat Dino and a Fiat 850 which are shown here. The red one is the Dino and the blue one is the 850.

I have searched the internet high and low and cannot find the 1967 Fiat BTM, so does it really exist?
