Just found this advert for one, which states a 9-seater for £31k, which largely fits with the original finance example posted in yhe op.
Vauxhall Vivaro e-Life Combi | Vivaro Life Edition | Drive Vauxhall
Yes, that is the one I got my CarWow quote for (9 seat Combi M) with metallic at £29,630. They don't actually do the passenger version with the larger battery, probably due to gross weight limits. The more expensive once is just posh, for the executive taxi market I guess?
I started looking at the 50kWh Vivaro-e Combi as I may need a larger vehicle in 2023 due to probable change of (part time) work which is why I still have a current CarWow quote.
However, I checked and the smaller Combo-e is probably big enough, a bit quicker and better spec. I then checked the e-Belingo which has same battery, etc. and for a top spec it is better value. Incidentally, Combo-e does not have Vivaro in the name, so I don't really see the confusion.
I found the Vivaro-e Life specs and price document and have attached for anyone interested. It is a HUGE vehicle for less than £30K!
