FYI: if you are interested, I have an update for your spreadsheet.
I have Certificates of Provenance for both of my 2011 Elise SCs. With the CoP, you get a letter that breaks down your car by model, edition, options, etc.
Both of my letters state the same numbers: Lotus built (35) SCs, (2) RGBs, (2) Type 25s and (12) SC Final Editions for (51) total U.S.-spec 2011 Elise SCs.
I could provide a copy of one of my letters from Lotus if needed.
2011 Lotus Elise SC (Ardent Red/Black 1 of 2 w/ Black Pack) 34k miles
2011 Lotus Elise SC (Storm Titanium/Magnolia 1 of 1) 13k miles
1994 Buick Century Special Wagon (White/Tan) Daily Driver 71k miles
