CREATE TABLE table_204_939 (id DECIMAL, "year" DECIMAL, "chassis" TEXT, "engine" TEXT, "start" TEXT, "finish" TEXT)

did 1979 or 1985 have the larger finish place ?
SELECT "year" FROM table_204_939 WHERE "year" IN (1979, 1985) ORDER BY "finish" DESC LIMIT 1
SELECT "year" FROM "table_204_939" WHERE "year" IN (1979, 1985) ORDER BY "finish" DESC NULLS LAST LIMIT 1
