I have something Coupe-related to sell but I have no idea what it is worth. I know how much the cost is new but that's all. Nothing similar for sale on here or on ebay. What's the best way to ask for a value whilst being mindful of not inadvertently placing a non-advert?

All I can suggest is that you put in an advert with a price based on what you are prepared to let it go for.

It won't cost you anything but a little time.

Supply and demand: is this something people are always asking for with little to no success? Chances are you can name your price.

If the opposite is true, chances are its probably not worth much.

We got rid of the haggling section several years ago Mark. Your memory is still fine.

Your reply beat my deletion Pete! Sorry, deleted it as I had just found the new rules. This place was all trees back in the old days

TBH it looks like it will probably be just as easy to stick them on eBay and see what they make.
