Actually, I came close to buying a Mercury Grand Marquis......big and smooth. Kinda like an ocean liner. The gas mileage was a detractant on that one. I think it was rated at 18 & 25, and the guy selling it said he was averaging 18.7 in mixed driving. Not bad, considering the size of the car, but still quite expensive, considering that I drive about 30k per year. I think the GM products probably get better mileage. I've heard of people with the big Chevy's getting over 30 on the highway.
