The Lucerne is quiet, and comfortable. It's as good as any import in its class, probably better. I do miss the 30 MPG highway and 20 plus city I got with our Park Avenues with the 3.8 engine. The best so far is 27MPG freeway driving and 17 city with this CXL.
I like the quiet comfort as well as the XM radio.
Get the 3.8 fuel economy back to where it was on the Park Avenues.
