I know of a few guys buying what they thought were Clubsport R8's with R8 and 340 badges on the boot and they were early GenF base models with SS seats. The untrained eye like these guys would have no idea that a manual wagon wasn't factory and thinking it's a rarity, they'd pay top dollar for sure!
It hadn’t even occurred to me that anyone wouldn’t realise it was non-standard.
I saw one used Holden SSV-R manual wagon for sale prior to buying our car mid 2015, not knowing at the time that Holden were no longer selling manuals I thought it was “rare” rather than “modified”. But I guess a super-enthusiast could have had the dealer convert the car prior to delivery, is it non-standard if it was delivered new like that? (another example of that … Volvo Straya had a lot of demand in the late 70’s for auto 242GT’s and manual 264GLE’s, neither available from the factory at the time, so they had a dealer swap the gearboxes for 50 cars … modded or not?)
There are plenty of people with a VF that’s not being used for the daily commute in traffic, and the fact that a manual is more fun would very much outweigh the fact that the car wasn’t delivered with a manual in the first place to people who know it’s not standard … an enthusiast would know it’s not a super simple conversion, and be happy someone’s done the hard work for them.
Originality might matter in 20-30 year’s time if petrol prices haven’t knocked the wind out of classic car values by then, but for now I reckon a manual swap in a wagon would get considerably more of the cost back come sale-time than stuff like blowers & cams etc.
