How can it be a rip-off...? Ebay's fees are clearly listed In the Seller Centre and in the Help pages, so you know exactly what it will cost before you decide whether to list or not. You're also shown exactly what it will cost at the end of the listing process, before you hit the 'Submit with £fees' button. So if you don't like what you see, don't list. Just sell your vehicle elsewhere. (I personally would list it on Gumtree, Ebay's sister site.)
It is a listing fee. If the car had sold you would have been charged a final fee too.
Consider - please - using a classified listing [£20] with no further fees. You cannot - even with social distancing - offer viewings. If you allow any contact details before the sale then eBay may sanction you I'm afraid.
