is there a resource to find the value of a used truck?

i am looking to sell my 07 freightshaker century class, and have an $18k bid for it.

specs on the truck:

series 60 detroit 515 HP
new self adjusting clutch
940k miles (and counting)
3.46 ratio
rubber has about 100k miles on it (i always replace all tires at the same time)
new exhaust manifold
new steering column
new radiator
new air filter housing
just had an overhead done
standard 100 gal tanks
fair condition( lots of paint peeling not to mention some dings and dents)

all in all its been a good truck to me, but its getting up there in age and has a ton of miles on it. i figure rather than waste $20K-$30k on a rebuild, i might as well get a newer truck that i want, that has some creature comforts.(possibly a volvo 2010 780)

can anyone who is in the business of buying and selling trucks give me a fair quote?

NADA offers online valuation for a fee. This is the same one used by dealers to determine valuation. I checked, and you can get appraisal on 3 trucks at a time for $40 online. Might be a cost, but you are getting the industry standard valuation service. Yes, they do valuation on class 8 trucks, not just autos.

who said you'd need a rebuild? keep driving it for another year or 2. thats just what i'd do.

 

940k miles is a lot for a freightshaker isnt it?

*E*

i honestly have no idea how many more students it can handle.
