Overpriced - undervalued?

[PURRFEKT01]

I bought a Samsung Galaxy Note5. I do not understand how a phone that cost me $800.00 two years ago is now only worth $175.00 (trade-in) today! I am very disappointed in this value loss. How are these amounts figured? It seems like I should have gotten some sort of compensation before this, if it was deemed so overpriced already. Are there any options for me? I have been reading horror stories about customers being told they will  receive $600+ trade-in from a VW rep or online and then, once it is out of their possession, being notified that it will less (from$175 to $11.00). I feel like I will be told I have to pay them to take it back!

1) how much is a new car worth after you drive it off the lot?

2) how much of a trade-in do you get when you want to replace a 2 year old tv??

3) in a non corporate store reps will lie to you to make a sale.

no options if you already made the deal!!!
