On the subject of objectively choosing an engine, how much consideration should be given to engine availability specifically to satisfy the production targets as presented in the Business Presentation?
My question is prompted by the realisation that it is relatively easy to source a wide variety of suitable current and obsolete engines in ones and twos from salvage yards but when it comes to buying brand new complete 'crate' engines, the field narrows drastically. Is it reasonable to base a business model on second hand engines, either factory fitted or customer sourced?
If not, and the model should be based on the assumption of a reliable source of new engines, does that source have to exist in the 'real world' or can it be make believe, like the business model itself?
