I've gotten 27 out of a late model Grand Marquis with the cruise set on 70. Those Ford full size cars do quite well on the highway. I'vehad experience with several of them through the years:
1988 Lincoln Town Car (My great aunt's car)
1989 Mercury Grand Marquis
1992 Mercury Grand Marquis
1996 Mercury Grand Marquis
2004 Mercury Grand Marquis
2006? Mercury Grand Marquis (Not sure of the year, but its not that old, and has less than 10,000 miles on it)
Grandpa loved the Grand Marquis, can you tell? All of the cars above would do at least 25 on the highway with the cruise set on 70.
