Some people buy a car and after a year or two start thinking about getting a different model, etc. The reasons could many. Maybe they got adopted a number of kids and need a larger car. Or they want to show off because they got a salary, etc. Now for a frugal person who is interested in saving as much cash as they can, when should such s/he get a new car? One blogger suggests that you should use you car until it's too old too drive. You wouldn't even sell it as a used vehicle. What you do you guys think? Would that be a great way to save cash?
