Towing with a Prius is Not Recommended by Toyota. But it can be done with light loads. Here is a video of a not so light load.

Likely a 2 year lease.... so long as you can Make Your Problem, Somebody Else's, it's not a problem.....
Around here, even regular VW transmissions are a lot of money to repair/replace. Good idea to check with any small car, but with a Prius, if I saw any evidence that a trailer hitch had been used, I'd pass on the car.
On the road, even just loaded with people, to me a Prius doesn't look oversprung in the rear - OK I'd expect for intended use, but not trailering.
