After looking over many of the luxury SUVs available. The LX is hands down the best "real" SUV you can buy. This 2000 vehicle has almost all the features my new 2006 sedan has (heated seats, auto dimming rear views) and some it doesn't (electronic stability control to prevent rollovers, ride height adjustment and real time dynamic suspension, and two independent climate controls for front and rear passengers). And even though a bit sluggish from a stop, it has lots of pulling power (80% of which is available at just 1100 rpm!), the sign of a "true" SUV with an engine designed for it, not just out of a truck. You will get use to the gas mileage.
Suspension system, 6 disc in-dash CD changer, heated seats, auto dimming mirrors, soft leather interior (doesn't feel like the cheap leather product of economy/mid class vehicles), real wood accents trim, decent sized tires (not those small car/truck tires the rest of the SUVs have).
It is hard to come up with some improvements to a 6 year old vehicle that outclasses almost every new vehicle today. This is evident by the fact that the LX models from 2000 to now haven't changed that much. Same basic engine, body, and suspension with only small improvements/additions.
