How much could I get for trading in a 2001 Toyota Solara SLE V6 to a smaller dealership?

[TJ]

I have a 2001 Toyota Solara SLE V6 that I bought about 3 or 4 months ago and wanted to trade it in for a Celica because it gets better gas mileage and I drive a lot now from college to work. When I had bought the car my dad basicly forced me to get it because he thought it was the greatest thing in the world, but i disagree and I believe I overpaid for it. I had bought this car for 6g. Now I am trying to trade it in and hopefully get around 4700 if possible to buy the celica they have. The Solara has 147,500 miles, sliding sun roof, one touch sliding/ tilt sunroof, leather seats, power driver seat, tinted window, day/night rear view mirror, power mirrors, power windows, remote starter, power locks, alpine headunit, new JBL side speakers, about 4 month old tires, new oil change and more that i cannot think of. The dealership that I bought this from gave me a recipt of all the things they did to the car which they spent 1000 even on. I know KBB gave this car about 3g for a trade in but I do believe this car would be worth more than that number. If anyone would know what I should look out to get or even an estimate on how much I can get out, that would be great. Thank you
