Remember, not many years ago, when American car shoppers could choose among dozens of new Detroit sedans? For the 2006 model year alone, General Motors offered 12 different four-door sedans, and that’s ignoring sub-models plus the sedans bearing the badges of (GM-owned) Saab and Suzuki. Today, there are three new GM sedans available here, and both of the Cadillacs are built on the same platform as the Camaro. The Buick Division got out of the US-market sedan game when the final 2020 Regal rolled off Opel’s line in Rüsselsheim, but the very last proper full-sized Buick sedan was Hamtramck’s own Lucerne. I found this Northstar-equipped first-year Lucurne in a Colorado Springs yard last month.
I’ve got a 2002 Cadillac Seville with the infamous Northstar engine. I bought it nine years ago and at the time it was four years old and had 30K on the clock. Before I even ask, I’m sure you can already guess what happened. At 149,000 miles the head gasket issue has reared its ugly head. For those readers who are unfamiliar, the repair requires the engine and cradle to be dropped, stripped down, and re-studded with twenty new holes. As opposed to timeserts, this fix is usually permanent.
