i'm going to need someones advice who had experiance about used car sales and knows what their worth. thanks...

I went to a used honda dealer today cuz i wanted to check out a type r they had. i asked the guy if they did trades, and he said ya. he asked what i had... i told him what i had and he said he could probably make a trade, but this was just a salesman, not the owner. he told me to bring my truck by tommorow and he would check it out.
specs on used type r...
2001 Type R, 16k, lowered, wheels, intake, header, exaust. paint looked to be in ok shape with few scratches nothing big. he said they wanted 23,000, which i knew they would never get. (this itr has been sitting on the lot forever.)

My truck specs...
2001 Silverado Regcab V8, 16k, lowered, wheels, intake, header, exaust and about 10g's put into the looks of the truck. it cost about 23,000 new stock.

What kind of a trade do u think the guy would do? im guessing he would probably trade cuz id think my truck would be easier to sell for more
