David Fox may be making the right decision here.
The question for me is whether I have enough saving to sustain a decent lifestyle in an adverse, yet possible, scenario (getting laid off, declining stock market, inflation, reaching an old age, high medical expense...). And incidentally, will the $60K car make me that much happier than the used one for half the price?
Even with a high salary, it may not be a very good decision to buy the expensive car.
