You can get a car body repair estimate online. You just have to know how to go about it. There are software damage estimators on the Internet into which you plug things like the area of the damage and the parts that were damaged (e.g., front bumper, front fenders, hood, windshield) and it will return what it thinks your accident repair will cost. It might even then contact several repair shops for you, so you can have a real adjuster come to look at the damage, or you might be able to contact your insurance company and they will send an adjuster in response to your email. It’s not quite all online, but at least it’s using the Internet.
