Final outcome was great - just took longer than expected to get the car repaired due to difficulty of finding parts for a 99 BMW.

Still waiting to get my car back in to have the hood and horn look at again. I have called again to reschedule as I had doctor's appointments and family health issues arise and could not make the last appointment
