You can buy a shiny new car and have that shiny new car smell, and the admiration of your neighbours. But if it is like most new cars it'll be a fairly humdrum, practical, do-it-all machine - and if like most new car purchases you'll buy it on some kind of finance which will cost you a sizeable chunk of the monthly budget.

Here's my argument against buying yourself a new car every few years and instead running two much cheaper cars on a fraction of the budget.
