I think they know people will pay for additional stuff so they just profit out of it. It's easy for them. My car will have minimal add ons although happy with it that way.
Be nice to know what the e Tron GT prices will be for comparison with regards to the service.
Suppose it's the same with any branding. Ones got a Porsche badge and the other an Audi badge. Porsche being the more premium brand and therefore more £££.
Both look nice however I prefer the Porsche looks.
