In my opinion they can not raise the price for the “early adaptors" without loosing a lot of the order. There are so many people that want that car more for the idea but for a real purpose which can not be fulfilled with another vehicle.As long as they don't add the inflation (we're at almost 9% in Germany ...) to the final price, I don't mind.
most of those early birds feel more like beeing a part of the Ineos team than as a customer.
For this reason the reaction to a risen price will be more emotional than fact based.
