Since this is a convertible, any issues will be magnified or exposed because of the convertible top. It will be very apparent if there is more than cosmetic issues with the damage if there is any new wind noises, any top up/down issues(shuttering, not locking right, alignment issues, leaks ect.), it will become very apparent. If you would like to get a different front bumper (thats if it is going to replaced based on the accident), I would talk to the body shop so you can have them not order the OEM bumper and order the aftermarket version you would like + any additional cost.
