Switching Rows as columns in SQL Server

CREATE A TABLE CALLED CAR 

CREATE TABLE CAR(ID INT,NAME NVARCHAR(20),COLOR NVARCHAR(20));

INSERT INTO CAR
    SELECT 1,'TATA SUMO','RED' UNION
    SELECT 2,'TATA SUMO','BLUE' UNION
    SELECT 3,'TATA SUMO','WHITE' UNION
    SELECT 4,'TATA SUMO','SILVER' UNION
    SELECT 6,'MARUTHI','BLUE' UNION
    SELECT 7,'MARUTHI','WHITE' UNION
    SELECT 5,'MARUTHI','RED' UNION
    SELECT 8,'MARUTHI','SILVER' UNION
    SELECT 9,'SAFARI','WHITE' UNION
    SELECT 10,'SAFARI','SILVER' UNION
    SELECT 11,'TATA SUMO','RED' UNION
    SELECT 12,'TATA SUMO','SILVER'

SELECT * FROM CAR

SELECT * FROM (SELECT * FROM CAR) p
    PIVOT (count(ID) FOR COLOR IN (RED,BLUE,WHITE,SILVER)) AS pvt
Order by NAME DESC

SELECT * FROM (SELECT * FROM CAR) p
    PIVOT (count(ID) FOR NAME IN ("TATA SUMO",SAFARI,MARUTHI)) AS pvt
