This is obviously a part in the works so it's fine if you don't have a picture of a finished part just yet. As a buyer, I would want to see pictures of a finished part before making a payment but it's ok to talk about interest in the parts now.
IKR, can you please post expected prices for the part and this will help generate interest and stay within the site rules for posting parts for sale.
You can structure it as a group buy by listing it as
1 buyer = $x.xx
2 buyers = $x.xx
3 buyers = $x.xx
4 buyers = $x.xx
5 buyers = $x.xx
6 buyers = $x.xx
and so on....
This would encourage members to work together on buying them as a group and give us an idea of what to budget and save for. I have some money budgeted for a spoiler and if I could get a nice LP670 spoiler for that price, I'd more than likely go with one of yours.
It's totally your choice if you want to list who's interested in buying them or not and this might be something you want to reserve for PM's to keep this list private.
Thanks,
Chris
