2014 Mustangs are still considered "new" vehicles and will have the bumper cover replaced with a new, OEM piece. Insurance companies will still replace bumper covers 3-6 years out, but will typically use used/remanufactured pieces, unless the customer comes up with the difference for a new OEM bumper. I have a 2014 GT/CS with 19,000 (Jan 2013 production date), and if someone rear ended me, State Farm would replace the whole bumper with a new, OEM piece. I hate paying out so I keep my deductibles at $100.00 collision, and $0.00 comprehensive. No matter what the year of the vehicle, if the damaged bumper is cracked or has a hole puncture completely through, the entire cover is always replaced for liability reasons.
