@DaveB I'm not sure what country you're in, but the US has some wacky laws about automotive dealerships and selling autos directly to consumers. At this point, only Tesla currently sells direct to customers, and that's because they invested significant money into lobbying and lawsuits and really played up the "built in USA" and "EV is green" angles to get the exceptions. But Tesla sells 1M autos a year at the current rate, so it makes sense for them to do that. I think there's two or three states that are still hold outs - including Texas as memory serves, which is super ironic since Tesla HQ has now moved to Texas and will be home to the largest Tesla factory by volume.
Ineos has said for the US, they'll be using a network of independent dealers. Based on what has been published here from the emails Europeans and Australians are receiving, my gut says US reservation holders will make the second "order" deposit direct to Ineos, and the final payment at delivery will be to the local dealer. For the US, it's possible the "order" deposit may go to the dealer rather than Ineos; this remains to be seen when we start getting our emails late this year (hopefully).
