Approximately how much is repair for a bent hood loose bumper broken front grate and scratched paint on a Toyota Camry?

Don't do it. I just got a quote from my local junkyard on a hood for a 91 Camry and they said it was $100. of course that's without paint, but you could find the same color car to begin with, since the Camry is so common. The bumper is probably another $100. The paint costs them $200-300, probably less. So total cost is $500 (without labor, just for parts, if you did it yourself) they are profiting over $2500 for something that can be done in a day or two.

I have a dented hood in a 99 Camry right now actually and I'm about to fix it myself.
