So, I've been following most threads about the roadster and am eagerly still looking for the roadster with the color and configuration that I would like to purchase, but have a few questions that I haven't really seen answered or addressed. Was wondering if the community has aggregated a detailed history of all the changes that have occurred to the roadster over the life of the production cycle, including running changes (say changes that occurred during a single series run, ie during the 2.0 series life cycle) and also obviously changes that occurred as part of a series change (i.e. 1.5 ==> 2.0 == > 2.5). Has anyone put together a comprehensive life cycle timeline with specific changes to include known serial number breaks with these changes. For instance, what is the difference in the BOM of a first series 2.0 car (around 500 s/ n break I believe) and a late model 2.0 just before the series 2.5 vehicles were starting to be built? Some changes were obviously marketed by Tesla, these should be easy to document, however, what other running changes occurred that might impact a buyers decision to purchase an earlier (or later) serial numbered car?
