The Chevy Lumina coupe and sedan were one of the cars that used the transverse leaf spring design. I would assume that the Pontiac Grand Prix and Buick Regal of the same vintage also used it.

I don't really know the advantages and disadvantages are about that design.
Advantages were weight savings, and compact design allowed for more passenger room in the rear, along with independent rear suspension allowing for a better (sportier) ride.
Disadvantage was that the tips of the leaf spring would break, leading to either noise, or faulty suspension. Cold conditions tended to make the springs brittle.
