Is it possible the FE and Base car will be built in parallel? If from the Lotus email the FE will continue for some time, and we're expecting Base cars in 2023 (as well as FE), then maybe the FE will be a flagship car at a premium price and the base will be car + paid options you choose? There will be people who want to buy an Emira the cheapest option with just the options they want, rather than the FE OTR £79k plus finance costs?
My first deposit was Sept, second Nov, while that might create a winter delivery its nice knowing I'll probably have all the info and choices (not to mention a drive) before having to commit the final decision, silver lining in being a late comer
