The comment on planned obsolescence:
I was thinking around your comments about their brand and its positioning in the market.
A big part of that positioning, so far, is rugged durability and longevity. This runs counter to the current auto industry, which (since the lovely W123 Mercedes) has moved towards the inkjet printer model of high portion of profits from parts, and declining lifespan of product, leading to shorter second hand product life, and therefore increased new car sales.
It is very difficult to prosper doing otherwise, as a mainstream player, in any market where this model dominates. However, INEOS is not aiming to be a mainstream player, and I think that their position will sustain a product that does not rely on short lifespan high margin spares*, mostly because they are at the upper end of the value proposition, low volume, and likely unable to satisfy enough demand to meet the really price conscious market soon.
