Bought my '04 with 43K miles as certified with 3yr/100K warranty. Now 2 yrs later have 78K and it still drives better then many new cars and SUVs. Very solid vehicle and very useful for cargo hauling (I own a small business with frequent airport trips with as many as 20 cases inside with rear seats removed and middle seats folded!). 3rd seats don't have enough leg room, but otherwise are Ok for short trips. Comfy seats with very tastefully done interior, large sunroof, very macho-looking from outside. Overall trouble-free 2 yrs with some minor wear-tear issues, like tires, brakes and some bulbs...great for snow and bad weather - feels very secure on the road with commanding view!
Lots of cargo, adjustable air suspension, rear height control, great view from the driver seat, love the wood/leather steering wheel, great heated seats, large reverse-tilting side mirrors, good headrests, exit tilt-away steering wheel, feels safe and sound inside and out.
Power-folding and auto-dimming outside mirrors, better center console storage, height adjustment for front passenger seat, Xenon headlights, 3rd seats to fold flat and power liftgate (note - all of these except the liftgate are now standard on the new 2010 GX460!)
