Is it possible that your individual reservation is high enough that it exceeds the production run of the initial version? How many roadsters were sold before Roadster 1.5 emerged, and was there a new reservation list for that version, did your reservation correspond to the version of car you reserved, or did reservation holders simply get notified that their version would be the upgrade?
My feeling is that after introduction, some changes will occur, potentially to hardware tech vs. software tech. Elements such as ACC, parking sensors, interior upgrades or materials changes could occur within the first year of release. The roadster went through two fairly significant interior design changes in it's short lifespan. My reservation is P7577 and it makes me wonder if what I see at introduction is what I'll get on delivery...
