Does anyone know why the Memory function is not available for UK market? Looking at Born V3
Probably cost cutting. The specs can vary between countries and the options are defined by build codes that the factory builds to. Examination of the build codes generated by the VIN if you can decode those build codes reveals what's different.
My pet hate is people buying cars without reversing cameras. They should never be left out for cost saving purposes and people shouldn't be duped into buying models with safety features paired back.
For RHD models the offer between Eire and GB is interesting one to look at to see what gets in Eire models against ours. Seat / Cupra can hold back the goodies by putting them in latter in the specs. Traditionally the UK did it's own thing. They decided what the customer wanted which isn't always what the customer wanted but what they could sell at the price or a bee in their bonnet about what they thought you wanted. I'd always buy the kitchen sink and it's annoying when it's left out.
