I wondered if there were any good financial reasons for buying a new rather than second hand car. I know almost nothing about cars - and really care very little about them either - and don't understand why people spend so much money on them. I have a 1997 car - it's fine, takes me around, causes no problems, and does what it says on the tin. I thought though that I might replace it this year - heard that SSIAs should mean a glut of second hand cars on the market, and thought I'd take advantage of it. But why will people buy new? Do you save money? Someone told me that if you buy new, then trade-in every 2 years or so it's cost effective in the long term. Is it? Or is the bottom line just that people like shiny new cars and don't really care what it costs them?
