Well, my brother has a 2013 Mustang (same thing as the one you linked), he hit a deer and insurance quoted about $6k in damage.
Headlights alone are going to be $1k, the fender was $320, the bumper cover was $400, and the hood was $1300 (we got a GT500 hood though). Paint will be in the $1k area, and we're doing installation ourselves to save that cost but one big issue we've run into is the radiator support is bent so I'm still trying to figure that out.
All in all what I see for you is $320 for each fender ($640 total), $600 for a stock base model hood, $400 for the bumper, $1k ish for headlights, then probably around $1500-2k in paint. This does not include any mechanical issues or issues I can't see such as bent supports. We started off buying pre-painted parts but the paint wasn't the same shade even though it was the same paint code so we wasted our money there, however the seller of the parts asked me to send in a piece of the old fender so they can paint match. If you're interested I'll give you their information.
