Yah, I doubt the value fell 5k in 5 months, you must have owed much more than the car was worth(upside down, negative equity) at that time so either way you eat it when you trade it in. If you're like me and put $0 down when you buy a new car you'll be upside down for a year or 2 at least. That's because new cars are about the worst "investment" ever
