There's not too much that's specific to Zoes. Open the bonnet and check the headlight mounts as those are the first things to break if it's had a bump. Check what tyres are fitted and what are required for the wheel size, e.g. the usual 16" ones specify load rating 91 (XL). I have seen 87s fitted as it comes up in a lot of vehicle databases, some say this is absolutely fine, others say it must be equal to or better than what came with it (91). I've never found a completely definitive answer so I prefer to err on the side of caution and check they're all 91 (and usually have to tell the tyre fitter when they replace one and their computer says 87).
Check battery SoH yes, it might be indicating lower than you'd expect but if you're armed with CanZE then check the firmware section for LBC (Lithium Battery Controller), the latest version is "Soft: 556". If SoH is lowish but the LBC version is old this indicates it needs the BMS (Battery Management System) update which will reset the SoH indicator to 98% and allow it to recalculate over time using an updated algorithm. User reports over the years, with one vocal exception, suggest this is effective. On my older Zoe with the same bug I had 70%(!) pre update, and then about 5 years after the update when I traded it in it was still showing 95%, dipping towards 90% sometimes in winter (warmer months seem to make for a healthier battery). You can get the BMS update done at any Renault EV dealer under warranty BUT your wording has to be quite specific. If you just go in just asking for a BMS update without context, Renault will refuse the claim and it'll be chargeable as they don't update what isn't broken. You have to specify that the range seems persistently lower than expected and try to nudge them into that particular solution (search "ZE50 BMS ACTIS"). Zoe specialists like DSG in Morecambe will know exactly what you're talking about, what to do and exactly how to word it so they get paid warranty money - but dealers may vary.
Other than that it's just generic stuff. Check the daytime running lights and headlights are working, overall condition etc. Drive and listen out for any unusual noises.
Mileage concerns are something I think EV drivers are still figuring out. In my case I can say a somewhat high-ish mileage for its age meant more general signs of use (scratches and scrapes in boot where things been loaded and unloaded, more trim rattles than other examples as things have loosened up over time, a little bit more motor whine due to slightly more worn brushes) but I'm more confident that if any underlying issues were present from the factory they'd have been encountered and fixed by now so I'm happy enough. I also don't have to worry about keeping it pristine as that ship has already sailed
