This only applies if they have an indication prior to delivery that you intend to sell it immediately. Once you've bought it and taken delivery there is nothing they can do.
I believe Lotus HQ asked UK dealers not to get involved in flipping cars. For example the yellow car that was originally on display in the Central Nottingham showroom, was on Autotrader and then went to auction on CollectingCars. That was not bought by the dealership but they were regarded as helping the customer flip it by displaying it. In that situation, it was a genuine change of circumstances and not someone flipping for a profit.
Other customer cars have been offered to dealers for re-sale and most have declined (I know one dealer who has been offered 5). It looks like one has ignored Lotus or found a way round their request. Hypothetically, a used car registered to the first owner and with more than delivery mileage on it might not count as a flip, but I don't know the parameters of what Lotus said to dealers.
