Diminished value is no joke. If I was you I would research diminished value and try to recoup another $1k based on diminished value. Take it to the Toyota dealership and ask them to give you a quote for trade in and how much is going to be taken off due to the repair. I did not do this when our 2007 Acura TL type S was rear ended by an Explorer. The other insurance paid for everything but when we went to sell/trade in later we lost another $1k in value because we are honest people and disclosed that it was rear ended. Also, keep the photo's of the damage. Although expensive, it doesn't look like the frame was bent. The photo's may help later to explain to someone when carfax pulls up accident data and you are trying to sell it.
I would sure have them go through the motor mounts,radiator,suspension and such to make sure everything is aligned and not leaking, bent or broken. You never know what rattles and problems may occur down the road from taking the hit. If you put it back to stock I would pitch for a whole new bumper cover, grill. I just don't trust a re paint job holding up a few years down the road on the plastic bumper. As others have mentioned, The shrockworks option would be very hard to pass up at this point.
One other thing, while our Acura was being repaired they tried to put us in a roller skate of a rental car. I had to fight with them to get a car that would safely carry 5 people.
My experience with insurance companies has not been very good. You are mandated to pay for it and then when you need it you get jerked around.
just my .02 from my past experiences. Good luck.
