When to trade in a relatively new car for maximum value
My suggestion would be to keep it. The value of a new car is that you get to drive it around when it's still new and shiny, and that you know its history. If you maintain it in good condition, both mechanically and cosmetically, then you can have both of those benefits for the life of the car. Your question merges the old car sale and new car purchase transactions together, but that's not correct. The value of your 2010 car has no relationship to the value of any new car you might buy, except incidentally through the market forces that act on each. The car dealership is likely to be skilled at making you feel like your most important criteria are satisfied, but they will try to construct the deal to maximize the money you pay them while making you feel like you're the one maximizing your value. Also note that the dealership cannot give you maximum value for your car, because it costs them money to sell it and they take all the risk. Some of the difference between typical direct-sale and trade-in prices is the commission you are paying them to both sell it for you and absorb the risks in the transaction.
