I had done carsure last month for the JDM i was buying. Two guys came on bike. A denter and mechanic.
I knew it had right fender painted, carsure denter said that bonut and fender are painted and other parts are ok. Interior was okay and reported likewise. Few small dents were also identified.
For sensors he put in the device and showed me no error history and explained it a bit to me. I was there the whole time though, though mostly inside car while engine was inspected.
Then in test drive mechanic marked only the brake pads being 50% used. I trust that coz car was skidding and I thought it was the tyres. So I was satisfied overall to say the least.
I think for ur case the bumper and lights come in fancy work and not body parts. So its not mentioned with exterior.
I was even reported muddy carpet, which I never expected so I am not sure how did they not mention the interior fault. May be seat covers are again fancy. You should have the person's number who visited. You should call them back and verify. It could be those workers not doing it right instead of pakwheels going down. Just saying.
When the guys finished the work he showed me the summary on his cell phone and I got an instant sms and email with link to my report. Mostly which i scrolled in front of him. Dont remember if there was a feedback.
I think the 'mistake' is you leaving the inspection. For me I don't trust nobody
