CREATE TABLE table_12357 ("Model" TEXT, "Chassis code" TEXT, "Production time" TEXT, "Number built" FLOAT, "Engine" TEXT)

What's the production time with more than 2.737 built and a 280s model?
SELECT "Production time" FROM table_12357 WHERE "Number built" > '2.737' AND "Model" = '280s'
SELECT "Production time" FROM "table_12357" WHERE "Model" = '280s' AND "Number built" > '2.737'
