so at the end of the car term get an interest free purchase credit card and pay the balloon payment on that. Is that a really bad idea? I want a car but have no available cash, dh and I have always beenm a bit afraid of credit (sensibly so) but last year we made a big purchase on cc and have had no problems paying it back in the time frame. Or is it just too risky, if there is no way of paying the balloon payment you are then either tied in for a further 3 years or car less.
