My lease will be up in a few months for my 2011 Prius 3. I'd like to stay with the Prius as I've been very happy with it. I use my trunk for work with back seats down and still have plenty of room. How much storage space will I lose going to the C? (I need to save some money so trying to get a lower monthly lease payment).
The only way to know is to load up a c with your stuff as a test fit. If your stuff is clean the dealer shouldn't have an objection.
