Based on that list, it looks like 34 Roadsters perished from Gruber Fires. I presume that includes both fires.
Yes; 6 in the 2017 fire, 28 in the latest, if we assume all the “Fire” cars in that registry are from the Gruber fires and not other incidents.
The 10 cars now known to have burned that weren’t already suspected are 139, 141, 231, 556, 781, 853, 985, 1048, 1311, and 1448.
Their registry also confirms the previously suspected losses of 430, 620, 925, 1216, and 1219.
If their entries are accurate, 1125 and 1211 appear to have survived by having been parked outside at the time of the fire.

For some reason 715 is marked as “Collission” (sic) on their registry; my notes have it as having burned in the 2017 fire - it’s possible it wasn’t fully repaired at the time of the fire, which would account for the discrepancy.
It would be nice if the registry noted that the burnt Roadsters were the result of building fires, and didn’t just spontaneously combust - might save some confusion and/or EV FUD-mongering down the line. These cars ain’t Bolts!
