120k miles, only minor problems. Have replaced the clutch and a set of tires (original brake pads still going strong!). Mazda 5-speed is not a smooth shifter but has been a solid gearbox. V6 is noisy and doesn't have a lot of power but seems to be a solid little engine, no issues with it at all in 7 years/120k miles. Did have a lean condition due to upper intake gaskets, but that was easily fixed in an afternoon with $60 of parts.
Brakes, gas mileage (16-17 city, 18-19 highway); may sound like crappy mileage but that is real life mileage (with 3.55 gears even) and is damn good for a full size. Interior is excellent - yep it's hard plastic but it all fits right and dosen't squeak and it's tough.
Crappy plastic clutch hydraulics - release point always changes and had the slave spring a leak which left me on the side of the road. Ride can be harsh when unloaded but nothing compared to my LS1 Camaro. Rides like a Cadillac with a full load.
