Read it carefully, I don't think he wants $4000 for it (I thought so at first too). For a trade he wants something that's valued at at least $4000. The title is $4000 probably so it shows up on searches for cheaper cars. Of course whether it's worth $4000 to begin with is another issue. Heck if I counted the hours I spent on my resto and pretended it was paid labor I probably "spent" over $50K as well.
