I like my miles eater - a 96 Volvo 850 turbo. 28+ mpg on the interstate, heated leather seats, legroom, cavernous trunk. I put one of those removable "canvas" (made from some synthetic fiber) seat covers on the back seat for the dog.
Cost me $3500 4 years ago, plus the usual maintenance on a 21 y/o car.
OTOH, if you want to go really high-end, a friend of a friend uses a Porsche Cayenne. Goes fast, rides great, and it's a real SUV that can go off-road (if you really want to).
