yeah..the mirada was the second to last RWD V8 car before ChrysCo went to the all FWD (k-car invasion) lineup. i believe that the diplomat was the last of the dodge RWD V8 models, but it was no sports car...
i think that the biggest factort is that GM refused to give up on the camaro and firebirds for so long...as well as all of those corvettes...
