Hi Shilps_mona,
There are two transactions..
First - Car is bought in the name of the employee's close person in whose name company provides the car lease rent..thereby maintaining the arm length's transaction..
Second..hire a profession agency like Orrus which provides the car to employees on the behalf of the company which has the option that after three years the car is sold to the employee at the written down value..
Regards,
Rajat
