I think Ineos knocked the ball out of the park on their first vehicle release. Few teething pains but all totally fixable.
Some things, like weatherstripping, are easily fixable in the aftermarket. Some things, like software, are also easily fixable by the manufacturer, but nearly unfixable in the aftermarket.
All that said, car manufacturing burns up a lot of cash fast, and needs unit sales to recoup all the up front costs. Let's say they've sold 20,000 units at a $80,000 factory ASP (to allow for some dealer margin). That's $1.6B of revenue. At 25% gross margin (which is generous in the auto business), that's $320M of gross margin dollars to date. How much design, production engineering, inventory, distribution, marketing has that paid for? We'll never know, and we'll never know what the supply contracts say about volumes.
I very much want Ineos Automobiles to succeed and sell another 100,000 units of the IG in the next 36 months. It serves all our interests! At the same time I would like Ineos to publish enough public information that we can keep our vehicles running for a couple decades if Sir James loses interest in fronting more cash to keep IA operating.
Fingers crossed this whole discussion is moot, but it's completely fair for us to worry how to support our Grenadiers for the long haul. More transparency would be greatly appreciated!
My neighbor has 3 original gt40's I can drive whenever I want... that is, if I can slice the top half of my head off.
