<prompt> Human: I have a 2009 Ford Fusion I am considering trading in for a 2014 or 2015 I at least know to go used and am curious if it would be deemed a sound decision from a financial stand point. My wife and I have 2 vehicles, with one having 180k miles, while the 09 has only 72k. I am advocating to trade in the lower mileage car as we will get more for it and the older vehicle is not really depreciating now that it has so many miles and still runs fairly well.  <response>: Why? Your 09 is fully depreciated. As long its reliable, keep it and drive it into the ground. Edit: You didnt want financial advice. You wanted people to confirm the decision that youve already made. Buying new cars is one of the worst financial decisions that you can make due to vanity and nothing more.
