I have an 02 explorer. It's great, but killing me in gas. So I bought a 4cyl Malibu. Did the math, took the paid off explorer down to liability only. When it is all said and done, my $158/mo. malibu payment + gas + insurance is LESS than my 02 explorer's fuel.
I kept the ford b/c I need it in the winter as I live in the mountains, and heck, its paid for. And the malibu can't haul what I need it to when I need it. BUT, I am Saving a LOT of money by having the new car. And, it's a 07 with 27000 miles on it and in gREAT condition.
