Please don't get taken by peer pressure and marketing BS around cars. 1st and foremost - put your focus back on your job and work towards ensuring it serves you long-term. Invest and invest well - ensure that you have some surplus for buying a nice house and living well (invest in a solid life insurance and health insurance policy (1-2Cr) for yourself and your family (think of your parents)- a lot of stressed middle/ upper middle-class homes make compromises right here to get by - bridge this gap if there is any in your setup). Use Uber/Ola/ the Metro. If you must buy, then go for a used car that's presentable, reliable and comfortable (check Spinny). Avoid the Germans and Swedes until you are comfortably making 80LPA. If ever you decide on going German, avoid VW and Skoda's India 2.0 cars - they are a compromise that isn't worth the premium.

I think the fiscal principle to apply to a car is that it shoudn't cross 30-35% of your yearly pay. That said if you're living at home and have no immediate expenses (such as rent / edu loan) why not - if you stay long enough in the system the 10L you spend on this won't be more than a blip, whereas the comfort of travelling in your own car is intangible.

Assuming this is not for mumbai - please PLEASE don't buy a car if you're working in mumbai, there's no way you'll survive your first year at a law firm if you spend an hour and a half / 2 hours a day in traffic behind the wheel.

Assuming you're earning around 15 LPA, rule of financial prudence says that max you should spend on a car is 60% of your yearly salary i.e., 9 lakhs for you. I think this is also too much. Get something like a second hand i20 for around 5 lakhs and you should be good to go. Second hand cars in decent condition are actually the best deals.
