    Cadillac CTS — Sigma / GMX320 (first generation) (2003–2007)

    The first-generation Cadillac CTS (Sigma, GMX320) is documented here from GM's service-manual RPO code lists for 2003 through 2007. The lists show 3.2L LA3 and 2.6L LY9 V6 engines in 2003–2004, a 3.6L LY7 from 2004 and a 2.8L LP1 from 2005, with 5 speed and 6 speed manual and 5 speed automatic transmissions. The NICB VIN manuals print CTS, CTS-V, CTS High Feature V6 and right-hand-drive CTS carlines; the 8 cylinder LS6 and LS2 engines are the CTS-V's. The 2003 right-hand-drive list is word for word the 2003 CTS list, so the two count as one source here. The 2005 list is the CTS list merged with the 2005 STS list. The 2005 list also prints a 4.6L V8 (LH2), left out because the Wikipedia article gives this generation no such engine.
