I purchased this former short-term rental vehicle with 13k miles on it in Dec '06. Now with 65k miles on it, the only thing that has malfunctioned was a headlight relay, quickly replaced under warranty. It's dead reliable, smooth, comfortable, great in snow and good at towing a 4k lbs, 26ft sailboat. Milage average is 19 mpg with mostly highway driving. Quality of materials and assembly is very high - the leather upholstery is actually better than that in my '04 Mercedes.
4.2 inline six is exceptionally smooth. Front seats are very nice.
Improve the hydraulic struts for the liftgate - they're kind of weak. Suspension is very soft which makes for a floaty ride and limits optimal cruising speed to 70-75mph.
