Selling Car Need Insights

I know this is a car buying thread but i cant find the rihgt place to place this. So if it's in a wrong place, please move it for me thanks. Anyway,

I want to sell my car which i bought 10 months ago. It was new when i drove it off the dealers lot. I am wondering which is the best way i can sell the car without losing too much money. I still paid off about 8k on this car and i still owe the dealership 19k. I've been trying to see how much i can sell my car for and i came up with 17.5k as the best offer.

The problem is my parents think i would be wasting my money because of the 8k + downs that i had already paid. Are they right?

Yeah, buying a car and then selling it a year later is not a good idea. Thats pretty much why people lease things instead of buying. If you're hell bent on selling it, I would atleast get the 19G for the car so you dont owe anything to the dealership. My question is though, if you were paying $800 a month, how did you end up upside down on the loan? That doesnt make any sense. You should be able to get more then 17.5 on a one year old 27G car.
