如何按一列和第二个总和进行分组？

Question

tsql新手在这里。

我有一个表，与此类似：

CarId CarName UserId RentedTimes CrashedTimes 
````````````````````````````````````````````````````````` 
1  Ferrari  1   2    0 
2  DB9   1   5    0 
3  Ferrari  2   4    0 
4  Audi  3   1    0 
5  Audi  1   1    0 

假设表被称为“汽车”，我想选择的次，每次车租给总数。根据上表，法拉利共租了6次，DB9五次和奥迪两次。

我试着这样做：

select CarName, SUM(RentedTimes) 
from Cars 
group by CarName, RentedTimes 
order by RentedTimes desc  

，但是，它返回法拉利的两排2,4为租时间等..

如何选择所有的车，总请各出租一次？

感谢
