Junkyard Find: 2006 Buick Lucerne CXS

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.

Sajeev,

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.

  • EBFlex "I've only filled the gas tank three times in 2500 miles"Assuming you went from 0 gallons to full (17.2), you have averaged almost 50MPG over those 2500 miles. 50 MPG in a Jeep Wrangler. To all of you EV nut jobs, tell me again how PHEVs are not the absolute best thing to happen to automobiles since the wheel. And tell me how they don't make EVs look like the awful play toys that they are.
  • MRF 95 T-Bird The Buick 215/3.5-liter aluminum V8 was one of GMs great engines. Unfortunately GM being GM in one of their greatest mistakes was selling off the tooling to BL. If they kept it around and improved upon it it would have been a fine motor for their compacts and midsize models through the OPEC oil crisis.
  • Chris P Bacon Not sure why a '21 is getting reviewed, because there have been improvements to the 4xe. I've got a '22 4xe Sahara. May 2022 build in High-Velocity yellow with a soft top. As soon as it was announced I knew I wanted to try it, not for the fuel mileage, but for the technology. I don't have a Level 2 charger, it charges fully overnight on the included Level 1. I see an indicated range of 27 miles regularly. Today it indicated 29 when I unplugged. I've only filled the gas tank three times in 2500 miles, a full charge costs me about $3 based on my current electricity supplier. I don't experience the rough transitions between electric and gas, so maybe Jeep figured it out? It's stupid fast when using all the power off the line. So much so that it will break the rear wheels loose when you stomp on it. I agree that plugin hybrids are the future. I see no need for a pure electric. This is the way to go.
  • RHD The word B R O N C O written in contrasting paint on the dashboard is quite unnecessary. The passenger certainly knows what kind of vehicle he or she is in. That detail is a big fail. The red and white Bronco looks great, especially with tires that have honest-to-goodness sidewalls on them.
  • Luke42 Aren't those trim levels just different colors of paint?That's what they sound like, at least. 🤷‍♂️
