Which Lucerne years have the 3.9L 6-cyl?

2009–2011, without a break — 3 model years in our VIN decode, across 21 factory configurations and 16,452 VINs.

What does a 3.9L 6-cyl Lucerne cost?

$6,990 is the typical asking price across the 189 cars with this engine on sale today. The year-by-year ladder above splits that by model year — the spread between the oldest and newest year is far wider than the spread between engines.

What is the engine code, and does it matter?

LGD — the code the VIN decodes to on the configurations on this page. It matters when you order parts or read a service history: the same displacement badge on another model can be a different code with different outputs.
