Yeah, I'd be surprised if that is totaled. I've had far worse damage be fully repaired pretty much back to new (aside from squealing belts on one of the cars). New hood, new passenger fender panel, cut and weld the front passenger support beam, etc. it's all doable and you'd probably never be able to tell. One of my cars had the tire tummy tucked in to the engine bay, a much bigger hit than that on your Fiesta, and it was repaired beautifully - no one but me even knew it had ever been in an accident.
On the other hand, I can definitely understand wanting to start fresh rather than driving around in a car that has been in an accident. I hope it works out for the best!
