As far as I know, BMW made the 524td in 1985 and 1986. I've heard rumors that they also made one in 1984, but I'm not sure about that. I've only seen one of them in my life, and it was a good looking car.

From what I've heard, owners of Rialta (?) RVs buy them up for parts because the RV is powered by the same BMW 2.4 I-6 turbodiesel engine.

Good luck finding one!

I think they were available in manual and automatic... not sure though.
