My dad's dream car is a Porsche 911, and he said that I can buy him one when I'm a surgeon (which is my future job of choice, but not for the money). So anyway, we were in the car and a 356 passes us, and he said "you can buy me that", I told him "that's over $500k", and he said "you'll be able to afford that". Ok...I'm buying a BMW 507 for myself before I buy my dad a 356. I however don't really expect to be able to afford a car of that rarity, you never know though.
DON'T EVER PROMISE YOUR PARENTS A EXPENSIVE CAR!!!! NEVER!
