I just got rear ended but i can't see any damage to my car?

It was a pretty hard impact. I have a 2008 ford escape but i have a 2inch hitch that took all of the impact. He was driving a vw toureg and his front bumper was smashed pretty good. I'm just wondering what could possibly be damaged on my car that i can't see like the transmission, brakes, electionics etc. I will be getting a mechanic to look at it through insurance. I have a slight concussion, neck & back pain from the impact so it was that hard of a hit. If i didn't have a hitch my bumper would be smashed in.

And you're expecting… What as an answer? You're already having the car looked at by a professional, so what can someone in here (who hasn't even seen the vehicle) possibly tell you that a mechanic (who will inspect the vehicle minutely) can't?

Will your car have damage from this crash? Yes it will. And a professional will find it, and they know where to look. They'll even be able to tell you how much it will cost to fix. That's kind of what they do for a living.
