Towing Sports Car

Does anyone have experience towing a standard transmission BMW Z3 or Mazda Miata with four wheels down? It would be nice at times to have a convertible sports car on trips. I am thinking of buying one and rigging it up as a tow dingy. Any suggestions?

This will be a poor reply sorry, but ill tell u what i've heard. I have a mazda MX6 that is a small sporty 2 door. The RV place here will not install a Blue Ox for me and the Mazda dealors know nothing about them. The only thing i could find out is that if it is a manual transmission your most likely ok and someone can do it. Where and who is what i'm looking for now.
