Is it standard for some Prius C's not to have the Power Button? I recently purchased a used 2013 C without the button or the keyless entry. This isn't a problem for me, just wanted to ensure it wasn't a red flag. Cheers!
According to the 2013 brochure, push-button start was only available on the Trim Three & Four. See http://www.toyotacertified.com/ebrochures/13_priusc.pdf
