I've just now finished using my 2004 Aerio Sedan and will now pass it to my daughter.
I bought it brand new and put almost every single mile on it myself.
Other than utterly routine stuff, I've done virtually nothing to this car.
Even the routine repairs may well be more due to my driving style than defects in the car.
As a matter of fact, I think I'm still using the original batter on the thing.
This has been a super car in almost every way that matters.
My favorite feature is also, ironically, almost the only negative about the car.
The high windows and spacious feeling of this car makes it feel incredibly roomy even though it is a tiny car.
Yet the high ceiling and windows also leave the car frequently blown around the highway in high wind conditions.
My only complaint would be driving in high wind conditions.
You definitely feel it.
Other than that - this has been a truly wonderful little car.
And I've now owned several little cars.
I bought my awd aerio brand new with 49 miles. It was loaded with climate control and ABS, I paid $15,000 for it. At first I had a minor hiccup with balding tires (tires went bald after 14,000 miles! dealer fixed it with alignment or something and its been golden since). This was my first new car and I am so glad I bought it. I have treated it well and changed the oil every 3,000 and got a tune up(spark plugs and stuff) at 100,000. I have went through some brakes and a few tire changes. The car has 140,000 miles on it and will be 6 years old next month. The car is great in the winter and I hope to get another 3-5 years out of the car.
AWD and Climate control is great. Sound system is good, I especially like the synthesized radio tuner and sub. The car is a good balance between power and gas mileage at 155 hp. I like that it comes standard with lots of features
Interior parts are little cheap(broken plastic covers in truck area all broke) The trunk hatch sticks constantly and need to be wedged out. The cd player also does not play when it is cold) MP3 aux connection would have been nice. These are minor issues though.
I purchased my 2004 Aerio SX new in June of 2004 and I love the car. I drove it from Columbus, OH to Cincinnati, Dayton, Mansfield, and Indianapolis, IN as part of my job as a manufacturer's rep until early 2009 and usually got 28 to 30 mpg on the highway. I have over 156,000 miles on the car and have had minimal problems (in fact the only one was the replacement of a catalytic converter), but I change the oil every 3K to 5K miles, and have had two or three brake jobs and one engine tune-up with new platinum plugs plus about three tire (all 4) changes. Even with all the miles it has had very reasonable maintainence costs. Too bad Suzuki dropped this model for a smaller version of it.
The performance of my Aerio SX is great. It is not that fast, but the handling is a dream. I can usually take curves at 15 to 20 mph faster than the posted speed. The standard options of rear window defroster and wiper, heated side mirrors, fog lamps, and vert. adj. driver seat are nice to have.
My only gripe is that the two cupholders are located in front of the shift lever near the dash so it is sometimes hard to get a tall drink cup in the holder.
