Welcome fellow sandgroper! Im sure that if your dad needs a hand we could round up a few mysandman members from the WA chapter and help clear that shed of all those old Holden bits

If you want a quick easy sale maybe one of those swap meets could be the way to go. Just rock up with a boot load and quit it. If waiting by the computer, hanging at the post office, waiting for couriers and people to show up you could try ebay and gumtree.

Good question re the spoiler. Hard to put a price on something like that. Let the market tell you!

Welcome and good luck
