VW doesn’t care, but they also can’t be held liable. Your only “concession” is that if you cancel, they can’t really charge you a cancellation fee.
It’s out of VWs hands, certainly the ID3 shares components with the ID5 and Born, but i fail to see how that is relevant to your situation. If VW can’t get the semi conductors, it can’t get the semi conductors – and VW obviously isn’t the only one having that issue – it just gets exacerbated by the sheer volume of orders.
We ordered a GTE Nov 10th 2021, and are still waiting. Exact same boat, got Octo Go, got a charger that’s probably out of warranty before we even get to use it etc pp – our options are to walk away and order something else which we almost did a week ago after a test drive of the Megane E-Tech that we could’ve had from stock (delivery before christmas), or wait as every other EV/PHEV buyer does with VW.
They’ll not knock off any money. You can obviously try, it doesn’t cost you anything, but i’d almost guarantee that they won’t – there’s no incentive for them to do so. If you cancel because they’re a bit dickish, they just keep the order going and sell the car for more profit from stock, you don’t have any leverage. That’s one of the reasons why we decided to wait it out – out of spite, to not give VW the option to sell the order to someone else (apart from the AP being too high on the Megane, despite being a genuinely cracking car).
I’ve had some slightly spicy communications with our saleslady in that regard, it’s not like i haven’t tried.
