Buick Enclave — VSS-S / C1XX-2 (third generation) (2025–2027)

The third-generation Buick Enclave (VSS-S, also written C1XX-2) is a three-row crossover assembled at Lansing Delta Township, Michigan, for the 2025 to 2027 model years in three trims: Preferred (1SD), Sport Touring (1SM) and Avenir (1SP), each front- or all-wheel drive. Every year carries the 2.5L turbo LK0 engine and the MF8 8 speed automatic, with 7-passenger seating (ABE). The codes come from GM's fleet order guides for 2025, 2026 and 2027 (published July 18, 2025, August 14, 2026 and September 25, 2026), checked against GM Authority's 2026 Enclave page and the NICB VIN manuals, which print the series as Preferred, ST and Avenir for 2025 and 2026.

Gaps: the guides print no axle codes, and paint and interior codes come only from each guide's color and trim page; each year rests on its own guide, and GM Authority's schedule puts 2027 regular production at July 20, 2026. NICB's pages carry the series and VIN positions, not RPO codes.
