Given the way the economy is sinking towards ground zero now, it's not a bad idea to ask this question. One source that I know of who shall remain anonymous says;
-Ford Crown Victoria/Mercury Grand Marquis
-Honda Civic (honorable mention to the Corolla)
-Toyota Highlander (if you absolutely need a SUV)
No surprise to see 2 Toyotas + another one that gets honorable mention plus 2 Fords and 1 Honda here. At least I'm not going to tell anybody to go out and buy a Golf or even a Versa.
