The Jeep Grand Cherokee is one of the best SUV's for general use. One I have now is a 1995, and good for another 10-20 years. They are reasonable in price, comparable with Toyota, Honda, Hyundai equivalent models and much cheaper than Lexus (perhaps the best of the class- esp. the sl. larger 400 series, when fit with heavy suspension).
I also had a 1985 Jeep Cherokee, which I sold last year, still serviceable.
Not quite as roomy as the Porche Cayenne but a hell of a lot cheaper (BMW, Mercedes SUV's also too expensive for me).
The Jeeps are superior to the poorly engineered but more expensive Land Rover Discovery (some of the heavy duty Rovers are good, but seldom seen).
