OP,
Selling on eBay, CL, etc. or a part it out depends on what are you looking for in terms of price. Certainly, a part out will yield you more, but it will take you much longer to sell, compounded by the fact that you will need to pack each individual item and shuttle it off to the post.....In my book, Time=Money, how much time are you willing to exert doing this?
Circling back to my first question if you are looking for under 500 a local sale may be the best bet....eBay has fees and so does PP.
Back to you. Recent sales show PX's selling in the 700 to 800 range, factor in the fees and time and that should guide you to your answer.
BTW bad front wheel will limit buyers.
Good luck with the sale.
Best, Ben
