accident question

im curious what internal damage would happen if a 5th gen got rear ended and its bumper, trunk lid, lights, cage is smashed from behind real bad?
will their be an effect on the suspension? im asking because ive never heard anyone replace suspension setup in an accident or anything like that...
thanks

Alignment can easily be compromised. If it was really bad, a bent frame is possible.

signal...hahaha keeping Round's??? Nice I can digg that ;)
