That sucks. But as far as I know you have a good few days to raise any issues you discover after delivery. If u can't push back on the 30 min thing then I would say make sure you get the contact and email of a senior advisor and loop them in on your further claims - and try to submit these as soon as possible (like within 2 days)
The only shortfall I can think of in this case is that more minor stuff (smallish panel gaps) might not be entertained later on (eg mobile service just claiming that it's within spec) - but if u raise that on delivery they might actually log it for u and mobile service might feel more obligated to fix it.
Fyi I took delivery of a M3P 18 months ago (Vancouver). I saw that my hood was indented and raised it to them 2 days later and they accepted it and gave me a new one
