I thought about that. I think thats a good idea. I noticed the left side matched the right in feel, could a low speed impact effect the opposite side where the impact took place?
I don't know other than to opine that damage on newer cars is harder to see...that said, if your body shop did not alert on anything other than cosmetic you are likely in good shape---they are in the business to repair cars, seems unlikely they'd pass a chance to do repairs if you needed them.
