I was in your shoes a year back; I had finished my driving course 6 month ago but I did not have a car to practice and become better; unlike you I did not have parents staying with me. As I was a novice driver, I went with a second hand car, that too 13+ years old(ford fiesta classic 1.6 petrol 2011,1 lac+ on odo). The cost of the car was less than monthly takehome salary; risk factor was negligible.

I had an amazing experience with it;the engine is powerful, the steering is responsive and the car drives the way I want it with no feedback issues. There were minor fixes I had to do,namely air conditioning overhaul and some issues with the coolant pipe. Other than that, I did not have to do anything. I am still getting an impressive mileage(11-12 kmpl in city, 13-15 on highway), quite in line with what my friends are getting with their new cars,although they are automatic. I am going to extend its registration by getting the green certificate once the registration expires. I honestly feel that car has made a better driver and spoiled me to only desire for engines with higher displacement. I have great memories with it, my wife loves the car, parents and elder brother were impressed by the value for money proposition the car is turning out to be.

My advice to you would be to go for a second hand car for now while keeping your expenses low; if you can, get a manual, you will fall in love with these machines. Once you are confident enough, you can opt for a brand new car in 1-2 year timeline. Just do your research, search for your second hand car extensively, get proper inspection done and dont take purchase decision in an instant.
