How bizarre, as there's no buyer protection for buying any class of vehicle.
Take a look at listing under a Classified ad format, see if it's more suitable. It's a slightly higher non refundable listing fee, but once sold, there's nothing else to pay.
One tip, if you do list as a Classified ad check and double check the listing, price, details, etc., are all correct as once live, no detail can be changed.
