Price
Value on these cars and trucks vary quite a bit. It really depends on a lot of factors as to how much one can get for an item.
The best place to check is Ebay, do a search for the like item and check current auctions and completed auctions.
This will give you a good idea of what to expect when you sell your item.
Keep in mind that when you sell your item you wont get the value of all the hopups and so forth. If you jack the price up you will get no repsonse and no bids on Ebay.
Its fairly common for people to come out on the forum and ask for just slightly under what they have in it. You wont get it, in most cases you will get much less than half of what you have in it.
Unless of course its in high demand or something special.
Good luck,
