Fill in the gaps

Pick a field and see every car the catalogue has no answer for. Set them all at once, change the ones that differ, and send the lot for review as a single batch.

Cars where the field cannot apply are left out rather than listed as blanks — an electric car is not missing a cylinder count, it has none. If you only want to correct one car, suggest an edit instead. To see which fields and makes are furthest from complete, start at what's missing.
