First Car Advice: Financing

Hi everyone, I am a new professional in the workplace (~2 years), and for my own independence and various other factors, I need to buy my own car. I already know the basic specifics of my car choice; I know which car model + variant to buy, along with the Showroom dealer and approximate on-road price of my choice of car.

As this will be my first car, I need to buy this with a loan. If it helps, my loan financing should be from SBI and I am choosing a Maruti Suzuki Nexa car.

I am looking for advice on how to go about financing this car payment via loan, i.e. what are the things I need to keep in mind in terms of the technical details of opting for a loan, whether I can directly opt for a loan with the help of the car dealer or keep the car purchase and loan sanctioning from the bank separate, down payment, etc.

Any advice is greatly appreciated!
