Car, car and cars

I think of most of the people in India, buying a car is really a big thing at least in my family. From the day I joined Maruti I force my dad to go for one. I suggested him an Alto as he can learn driving and may be after few years we can upgrade. But his answer surprised me.
“Naresh I think, Alto is little puny and I think I will go for SWIFT”

This happened at around 2008. And I succeeded in end of 2009. And still he feels that it is something a sort of expense rather than a need. (Unfortunately the SWIFTs have become hot selling car in recent times that we have a huge waiting period).
This is one part

Second one, a car for me, to use in Gurgaon. (Gurgaon has one of the worst weather conditions, best roads and good must visit places in just a 6 hrs drive which makes it a need rather than a pleasure toy). I started to hint for a car to dad once I finished my training. My dad never refused but he did not comment as well. I saw some of the second hand vehicles Altos, Wagon R etc (but only Maruti cars as I can understand and service small issues by myself) but every thing I felt like shit. I told my father I am going for a newly launched vehicle and he said OK.

Now the confusion starts.

Should I go for a vehicle that costs about 3.5 ~ 4 lakhs or should I save?
Am I going beyond my limits?
Will a car turn to be a burden?

And to add to that my sister also confused me.

“Naresh do you really need it? You are so young to own one? Save money? What will happen if there is economic slowdown again? What will happen if you bang somewhere and cry for help (Ladies have their own imagination)”

I also think car is not a necessity.Also I love cars. I want it. So I need it. I trust the future is great and I do not go bankrupt because of buying a car. I feel I am missing a car badly.

Ohh sister I am buying just a car, not an airplane.
