Yes you can surely opt for a car loan as a non resident Indian. Before applying for a NRI car loan, make sure you are eligible as a NRI. For that you would need to check whether you have spent more than 182 days outside the country in the relevant tax assessment year. It is also a good idea to check with various banks before selecting the bank or NBFC as some banks have a minimum time cap you need to spend overseas before being eligible for a NRI car loan.
As an NRI car loan applicant, you will have to make a relative preferably one of your parents as a car loan guarantor or co-borrower. You would need to purchase the vehicle in their name instead of your name as onus of repayment would lie with them. The EMIs of the car loan would be deducted by the bank from your NRE account. The co borrower of the car loan is also allowed to repay loans on your behalf.
