Should I buy a car?

Just like the Lynch Law, whenever i make progress / try to make progress in my life, the opposite happens to the market or the people i am associated with. I joined UBS ( a progress in my life) but the company reported a loss for the first time in 9 years with close to $ 4 billion in losses. Now, last month finally i zeroed on gifting myself a car, then guess what, oil prices started increasing touching all time highs. With oil prices touching $93 a barrel and with every possibility of touching $100, i wonder how the world looks like if i actually buy car. Hope i dont end up buying a car and keep it at home as a decorative item... only time will tel .. ...:-)
