The most common (and realistically feasible) method of buying a car is to buy it with a loan/credit card, then pay it off in bits every time interval.
However, say that I could buy a car in full when I've fully decided that I should buy a car. Should I? Of course you will save up on interest that would have cost you a lot otherwise, but am I missing anything? Are there any disadvantages to buying big items in full?
Take note that this question doesn't only apply to cars. It applies to big things in general.
