Good tips. I think however people put too much credence on seeing XX7 on Acacia Ridge plates. For a start there are Acacia Ridge built XU3's out there, and these are identical in spec to XX7's prior to 10/75 (basically a 9/75 XX7 plated HJ is identical to an 11/75 XU3 plated HJ. XX7 after 10/75 is the orphan). There is no reason an obvious Sandman from other assembly plants shouldn't be worth as much. It makes no difference to HQ GTS 4 doors or SS's if they are built in Acacia Ridge, Elizabeth, Dandeonong or Pagewood so Sandmans will be the same. To a buyer that knows what they are looking at, an untouched Survivor Pagewood assembled HQ van will be worth the same as an Acaia Ridge assembled one but otherwise identical. Turn the Acacia Ridge one into a 253 and make the Pagewood one a 308 and auction them off side by side. The 308 will will pull heaps more than the 253. To me the most valuable will always be the 308 examples, regardless of series. HQ V8 will probably always be the most sought after, probably equally shared 2nd between V8 HJ Kingswood ute and V8 HZ Holden van with the rest coming closely behind by personal preference after that. Probably the least popular in the end will be a 202 HX or a 173 drum brake HJ Holden ute or van.
