Buick Somerset: 1985–1987 two-door compact and its successor Skylark
Buick Somerset (initially the "Somerset Regal") — the two-door compact Buick coupé introduced in 1985, built on the N platform developed by Oldsmobile. In 1988, it was renamed the "Skylark". This article covers its history, engines, related versions, and what buyers need to know.
Somerset in brief
The name "Somerset" originally belonged to the "Buick Regal" trim package. In the 1985 model year, the old two-door "Skylark" coupé was replaced by the "Somerset Regal", built on the N platform developed by Oldsmobile — this was a front-wheel-drive compact with a more modern, aerodynamic look and "long hood, short tail" proportions.
In 1986, the N platform was also adopted by the four-door "Skylark" sedan, and the two-door car dropped the "Regal" suffix, simply becoming the "Somerset". In 1988, the "Somerset" name was discontinued, and the two-door car was renamed the "Skylark".
How the versions differ
The Somerset (1985–1987) was a two-door coupé, while the four-door sedan equivalent was called the "Skylark". Both cars used the same platform and mostly the same engines, but the "Skylark" sedan came with standard analogue gauges, while the "Somerset" had a fully digital instrument cluster.
The 1987 four-door Skylark offered the sporty T-Type version with a V6. In 1988, when the Somerset name was discontinued, the two-door car started being called the Skylark, and the T-Type was replaced by the S/E package. This generation of the Skylark was produced until 1991.
Engines and transmissions
The main engine is the 2.5-litre Iron Duke four-cylinder, sourced from Pontiac. It was paired with a 5-speed manual gearbox supplied by Isuzu. Optionally, a 3.0-litre Buick V6 with a multi-point fuel injection system (around 125 hp) was available, which was only paired with a 3-speed automatic transmission.
Later in 1988, the Oldsmobile 2.3-litre DOHC Quad 4 engine (around 150 hp) was introduced, and in 1989, the 3.0-litre V6 was replaced by a 3.3-litre V6 (around 160 hp).
What to check when buying a Buick Somerset
As this is an older American compact, the body and undercarriage are key: inspect the sills, wings, and floor. Also, check if the body hasn't been heavily repaired.
The engine (especially the Iron Duke and V6) should run without major issues. The digital instrument cluster is one of the weaker points due to age: check if it operates with all functions, as parts may be hard to find.
Parts availability: many mechanical components are shared with other GM N platform models, so this is eased by networking with American classic car clubs.
