mysql - 如何使用 GROUP BY 检索按字母排序优先的结果集

Question

我有下表

SELECT * FROM cars;

id      value
1       convertible
2       van
2       wagon
3       scooter
3       segway

当我使用GROUP BY语句

SELECT * FROM cars
GROUP BY id;

我得到以下结果集

1   convertible
2   van
3   scooter

如何更改上述语句以选择按字母顺序排在最后的 cars.value？例如

1   convertible
2   wagon
3   segway
