I wonder if either transmission Mirage will have a tow rating... I'm guessing "no", officially.
People put trailer hitches on all kinds of small cars that don't have official ratings. Owning a light trailer is a good option that allows you to own an efficient (usually small) vehicle for 99% of your needs, yet still move bulky (if not heavy) items when needed.
I have a light (160 lbs empty) trailer that I use to move all kinds of things ... fairly light things, obviously:
Pedal boat...
Tree/brush trimmings...
Small sailboat ...
