This is my second Lucerne. I still have my first. I just couldn't bring myself to trade it in. I just love driving this car. It has been an absolute joy. It is so quite and smooth I sometimes forget that I'm driving. Whenever I give anyone a ride they cannot believe how nice of a vehicle it is. Last year I drove my '06' on a 3000 mile trip and averaged 32 mpg at 75 mph. I was astounded. I think the '09' will do better based on what I have experienced so far. I shopped hard for a new car in '06' and as soon as I took a test drive of the '06' Lucerne I bought it on the spot. After two months with the '09', I am not sorry.
Cooled seats. Nav system. Blind side alert. Quietness. Handling.
My '06' came with Heated Washer Fluid. That's only thing missing on my '09'. Alas.
