Craig there is a maximum final value fee of $250 on any item not listed in ebay Motors or Real Estate. They do sometimes offer special promos of $50, $100, or $150 final value fees to sellers that have an ebay store.

Selling a car is entirely different:
It is a successful listing fee of $60 for any car up to $2000 and $125.00 for any car over $2000 for first 4 listings every 12 months. Starting with your 5th listing there is no final value fee, only a $50 insertion fee per car.

Ebay does provide a calculator to show you the fees for any item you list excluding ebay Motors and Real Estate.
