Stingy money-minded Indian parents just won't leave me alone. How do I get out of this?

Anonymous
I'm a 25 year old Australian of Indian heritage, just finished uni, just started working and making my own buck.

When I was in school, my parents neglected me big time. They wouldn't spend a cent on anything that didn't contribute to my studies or future. That meant no cosmetics, sports ( not even at school coz you have to pay for equipment + membership + transport fees), dance, music lessons or instruments, or even the school formals. No lunch or pocket money either. I had to take food that was cooked 3 or 4 days ago and stored in the fridge. I wasn't allowed to go out (transport + food + fun expenditure) or hang out with guys. If I did want to hang out, which was only possible 2-3 times a year, I had to get approval for every cent I asked for and tell my parents what it was for, then come back and report to them what I spent it on with receipts.
That was my life.
Even if I wanted a simple plant for my room or curtains, my parents would start a huge argument and start shouting about how it's a waste of money and won't add value to the house or contribute to my future.

While at uni, I had to live under my parents' roof coz I didn't quality for living away from home, thanks to my parents' income/assets (go figure!). I painstakingly lived it out, living up to their stupid expectations of behaving like I was a poor girl in India. No dating. No car. Not allowed to work (as they feared I might fail uni).
That was it.

Now that I'm making my own money, I want to buy my own car. I want a used car, so that I'd have more disposable income. I asked my parents for advice on buying a car. They objected fiercely to an old car, as it won't give the family status and "might breakdown and land you in an accident". I'm like "it's my money..I just wanted some advice". Them: "SHUT UP. I know it's your money, but don't disrespect me, idiot".
I bought the latest ipad and they were like "there are cheaper computers. why did you waste money?"
Ughhh..HELP ME!!!

This is lame, but I don't feel like I'm ready to move out, as my social skills are terrible thanks to my parent's overcontrolling attitude. I want to eventually, but one step at a time. For now, I need help on dealing with my parents.

Even if I move out, I'll still have to know how to deal with my parents.
Every time they notice me buying something new, be it clothes, electronics, cosmetics etc, there's a huge argument over its price, and how there were cheaper dealers (by $3)
