Can you upgrade some of the things on the 2013 Prius C One to have what the Two version has. As far as like the Power Steering, and the Center Console? I've heard that aftermarket power steering can be put on, and the center console can possibly be upgraded. Is this possible?
If.....you have a "trim level" 1 Prius C and it doesn't have power steering, there is something broken that needs to be FIXED, not modified. Cruise control seems do-able, based on some previous posts here.......but it's likely that anything more than that and it would be better to "upgrade" the whole car.
