So I was ready to pick up my MY this morning. Inspections went well, there were some minor paint chips and slight misalignment of a tail light. I asked them to fix the tail light before acceptance, which should not take long. On my way home, they called and told me the roof glass was broken while they were trying to fix the tail light alignment! Now there are 2 options: 1, have them replace the roof glass, which is about 1 week; 2, reject this vehicle and wait for a new vin. My question is, how could the roof glass be so fragile? Any suggestions on what to do next?
