I just want a chart of total maintenance/running costs per model.
Also maybe a chart of "uptime" per model - ie. how many days in the year on average was it drivable, vs in the shop being repaired/inspected/waiting for parts.
Does anyone make that?
There is an ADAC report, that reports the number of road-side defects per car type that the ADAC was called to fix: https://www.adac.de/rund-ums-fahrzeug/unfall-schaden-panne/a...
And they do provide some statistics about running cost: https://www.adac.de/rund-ums-fahrzeug/auto-kaufen-verkaufen/...
However, both aren't that trustworthy, just better than nothing, because:
The first one about road-side breakdowns is frequently gamed by car manufacturers, because in leasing and warranty contracts they often require the use of their own road-side assistance orgs, thereby bypassing ADAC. So the more expensive German manufacturers are definitely underrepresented there.
And generally, ADAC has been known to produce unreliable tests and statistics: https://www.focus.de/auto/ratgeber/sicherheit/neue-vorwuerfe... https://www.sueddeutsche.de/auto/neue-enthuellungen-sind-auc...
So generally Tesla Model 3/Y appears one of the best in that report...
I assume the denominator is cars registered with ADAC, rather than all cars in germany? Presumably that means those with lease contracts requiring another breakdown service wouldn't affect the stats?

Not quite, the denominator is the number of road-side assistance calls they get.
ADAC has a driver membership system, where you get that assistance for free as part of your membership as a driver. You can still call them as a non-member, and I suppose those calls will factor in the statistics as well, but that is expensive, so it's rare. And you don't register your car with them, so they don't know what their members are driving, you just tell them your membership number and can get assistance for whatever car you are currently driving in.
