My 06 Azera got hit in the rear just over a year ago. The girl was texting hit me only about 4 mph. Did look like much at first matter of fact I didn't see anything but a small mark by the license plate from her car.
Then I took it to my body shop who does a great job. When we opened the trunk the speakers were all down inside the trunk, the padding under the trunk fell down, and the bumper had creases in it from the impact something that I didn't see but when he held a light on the bumper you could see a wave.
I was sick and the damage was $1800.00 not much but again it didn't look like much. Then one month later the rattles started. Took the car back to the body shop and he couldn't find out what was loose so took it to the dealer. They had it for a week and no luck. It was something either under the car or in the rear end.
I had three cars that were hit all repaired and one thing is for sure they are never the same.
I was so ticked off that my car was hit almost sick as I liked the 06 Azera. So happy with my 13 Azera sure hope nobody hits my car again.
