Got Rear Ended This Morning; Update: Met at Lunch

And like an idiot I didn't call the cops to file a police report. He asked me to keep the insurance company out of it. I did get a picture of his insurance card. We were on the side of I-35 and I was late to work, so I wanted to get moving quickly. I got his phone number and insurance card pic then bounced. I drive a Mazda CX-7 and he was driving a Toyota Tundra. I stopped for a traffic jam and he hit me going about 5mph. Minimal damage. We noticed scratches on my bumper and that the sides had popped out. Once I got to work, I took a closer look at saw cracks under the lift gate of my back door as well as a dent on the back door. Now he is claiming the dent is too high to have been from his truck. Meeting him at lunch in the mall parking lot to see if his trucks grill lines up with the dent on my back door. Never dealing with this again. Next time I'm just calling the cops and following the standard procedure. Try and be nice and you might get fricked.

Update:

We met up at lunch in the mall parking lot. He is telling me there is no way his truck caused the dent to my back door and cracks in the lift gate. I told him I can go get an estimate and he can pay me or I will have to call the insurance company. Looks like I'm calling the insurance company. frick this guy. Here I was trying to be nice. This dent and cracks in the lift gate are new damage. I've never seen them before on my car. It happened this morning. I just hope the insurance company doesn't frick me now.
