Planning to buy a car (15 lk), going by cash is good or taking a loan is a better option. This is almost 65 percent of my savings...

I don’t think giving 65% of your liquidity away is a good idea. Make maximum down payment which would still leave a healthy emergency liquidity with you. Take a loan not more than 5 years (try to close in 2 to avoid pre closure charges). Try building the pre closure amount in any safe asset.

If you decide to go for loans/emi just ensure your emergency fund is sufficient for fulfilling your needs and the emi/loans for at least 6 months. It's a very volatile job market, and layoffs are sudden.

Never assume you couldn't/wouldn't be the one (to be fired).

If I were you, I wud buy a cheaper used car and upgrade after. But if you have your eyes set on the 15L car, buy with a loan cheaper than 9-10% rate.
