Re: another sud ti on ebay
It is certainly not a standard 105 Ti QV in that colour scheme and lacking the pax mirror; but that isn't necessarily to say it isn't original. One possibility, if it is an "original", is that is was a dealer special to move on some slow moving stock of the less popular SC variants in the least years of the Sud.
I recall a friend having an Alfetta GTV built at the transition from chrome to plastic bumper that looked externally like a late model one, but had an earlier instrument cluster, the UK dealer network put together a bespoke dash to group the earlier separate centrally mounted instruments (only revcounter was in front of driver) together in front front of the driver so it looked like the eventual layout.
If this Sud is one of those transition specials it would be quite unique, though it would need the documentation to back that claim up.
Another possibility is it's an overseas RHD model where they might have offered different schemes to the UK market.
