Year 1 and year 2 are the biggest hits for depreciation on any car. After 5 years the car is fully depreciated.

Also, don't use Edmunds to determine your trade in value as it's not always accurate. A car's only worth what someone is willing to pay for it. If the market is flooded with excess supply or there are excessive discounts on unsold new inventory holdovers on dealer lots, that's going to impact demand - and ultimately the value. The best way to figure out what it's worth is what the same car is selling for at dealer auctions.

In my region (the northeast) Galves is probably the most common dealer auction service. It used to be closed to the public but now you can sign up on their site for a few bucks for a day to search their database to see what the last Camaro optioned like yours sold for.
