 I have owned my amanti for 4 years now.  I bought it with 50K miles on it and now has 125K.  The car has every option available at the time, sunroof, all power, a great stereo, leather seats, etc.  It runs very well and acceleration is very good for a car this size and weight (almost 5,000 lbs).  You will feel secure when driving this vehicle.  Its seats are extremely comfortable, front and rear.  5 adults can travel in it, very comfortable.  I carry stuff all the time, I really appreciate its huge cargo trunk.  Fuel economy is poor, around 14 mpg in the city, but much better on the highway, around 22.   I have had to change batteries in my car every year, I still do not know why.  The outside chrome trim peeled off a few months ago and the air bag light is always on, apparently this is a problem in these cars.   Regular maintenance such as oil changes, filter changes, brakes, tires like any other car at regular intervals.  I did have to change its mass flow sensor and front cv axle joints and engine mounts, those were a bit expensive.
