Try this,

SQL

DECLARE @a INT;
SET @a=1;

SELECT * FROM vehicles
WHERE 1 = 
        (CASE 
              WHEN @a=1 AND company IN (3,4) THEN 1 
              WHEN @a=2 AND company=2 THEN 1 
         END)

Happy Coding!
:)

Might be this should work.

SQL

declare @a int
declare @str varchar(30)
declare @query varchar(500)

set @a=1

set @str = '2'

 if @a = 1
 begin
 set @str = '3,4'
 end

set @query = 'select * from vehicles where company in (' + @str + ')'

exec (@query)
