I imagine Mr Renter will be interested in this question even more so than your good self? If it was me: I’d be first on to my own car insurer who I expect would cover me and proceed to repair quote stage, if I was covered for such, and just pay to fix the car. They usually thereafter decide if it’s worth their efforts to come gunning for the body corporate’s insurer for recompense them but that’s not your business as much as it is your insurers. The non-car items would likely be covered by his own household contents insurance (some have this, some don’t – but as here, they should) and they too might pay out then come gunning for recompense. End of the day, your property needs be made sound or your insurer may just not pay up if they say you aren’t up to speed on your required maintenance and they remained unaware of that.
