I think most of the responses so far would support the above advice. I don't mean to trivialize the damage to you car. But like others have stated, its just a door ding (actually not a ding but from the looks of it, a paint gouge). It sucks that it happened to your car but it is the price you pay for operating a car in a society full of idiots. Don't get me wrong, I'd be mad too.
If you really want to pursue it via the insurance route then do this. Go to 3 high end body shops in your area for estimates. Paint on plastic surfaces are extremely difficult to match with metal surfaces so they have to repaint both the door and the plastic cladding that was scratched. Then they'll have to blend the paint onto the body panels on either side of that door. If they don't, you'll see an obvious difference in tint, surface texture and gloss. Present the estimates to her insurance adjuster and tell them you will settle the case for the average of the 3 estimates. If they decline then tell them you will take it to the highest shop and go through your insurance company.
So once they settle the case with you and cut you a check (which will probably be around $500). Go your local Toyota dealership and buy a can of
Natural White (056) Touch-Up Paint P/N002580005621 for about $8. Touch up the scratch and keep the paint for future scratches. Then take the rest of the cash and take your wife out for a weekend get-a-way. :cheers:
Seriously though, you probably want to avoid the insurance/body shop route. The end result may not be to your satisfaction. I have never had any body/paint work done where I was satisfied same as factory. You'll be out a car for a week. You'll have repainted panels and a carfax hit on your car's record which may affect resale value.
The "$100 and touch-up yourself" is really a sound piece of advice.:thumb3:
