Table schema:
CREATE TABLE table_name_17 (points INTEGER, winnings VARCHAR, laps VARCHAR, make VARCHAR, car__number VARCHAR)

Question: Which is the lowest point value that had not only a Chevrolet car, but also a car number smaller than 24, total laps of 312, and a winning purse of $122,325?
SQL: SELECT MIN(points) FROM table_name_17 WHERE make = "chevrolet" AND car__number < 24 AND laps = 312 AND winnings = "$122,325"
