To Whom It May concern:
Unless otherwise incorrect, I believe the blonde in the Kia Spectra commerical is Amy Farrington, an actress who appeared in 'The Michael Richards Show' and played an ER doctor in 'Soul Survivors'
However this information is based on text and not pictures. It may not be the same girl. I'd have to rent 'Soul Survivors' first. You can verify this info with the Internet Movie Database (link below) and click on 'other works.'
