Cadillac XTS — Epsilon II, enlarged (2013–2019)

The NICB VIN manuals list the Cadillac XTS from the 2013 through the 2019 model year, in front- and all-wheel drive, as Base (Standard from 2014), Luxury Collection, Premium Collection, Platinum Collection (Platinum Edition from 2015), a Livery series, twin turbo series from 2014 (Vsport from 2015, V-Sport from 2017) and, from 2017, Luxury, Premium Luxury and Platinum. The repository holds no GM order guide or RPO code list for the XTS; the one XTS factory document, GM's 2014 Car and Truck Guide, prints the eight 2014 paint colour codes (and a ninth, Summit White, for the Livery/Limousine model) but no options or packages, so the other rows come from GM Authority's RPO Central articles, which print GM's RPO-level change list for each model year from 2014 to 2018 (and for the XTS Professional livery and coachbuilder models), from Wikipedia's engine table, and from the NICB livery series; there is no source for 2019 codes. A change list dates a code to the year it is new, changed or deleted, so most rows carry one or two years only; the years between them are gaps, not claims.

• chevrolet/2014-gm-fleet-car-truck-guide-copy-xr793.txt — GM 2014 Fleet Car & Truck Guide (xr793.com copy), XTS page 50 and XTS Livery/Limousine page 117; prints the 2014 exterior colour codes (GAN, GBA, GBE, GBN, GLJ, GLK, GWT, GXH; GAZ on the Livery/Limousine page) and prints no options or packages
• Sibling mention only, not a source for any row: the 2014 Impala fleet order guide (Wayback capture) prints LFX for the Impala, named in the LFX Notes as corroboration of the code
