A little more information would be useful and the answer is still going to be it depends. What year is the motor, how many hours. Do you have a Honda mechanic close by? What shape are the tubes in. Does all the wiring work? Do the tubes hold air, can you run them for a year or two or do you need to replace them now. Condition of the trailer, wheels, bearings, is it registered.
$8K would be fine if everything is in good shape. I'd work downwards if any of it is a project.
