Although I've only owned my Aero for just over two months, I've had some good experience with what this car excels at and what may be trouble spots. With all its gadgetry, I've already had my share of glitches, most notably poor performing rain-sensing wipers, a result of a poor sensor. Various electrical gremlins also pop up on occasion, but are mild irritants at worst. The 9-5 in Aero guise is a great looking and oddly rare car in the sea of Bimmers, Lexii, and Benz that swarm the roads of Atlanta. While in no way a neck-snapper, the Aero has plenty enough zip to best most 'sporty' sedans on the road. Where it truly dazzles is doing this and still returning 30mpg on the highway
Performance is extraordinarily balanced in this car. Handling, accelleration, and highway cruising are simply excellent. The icing on the cake--and never seems to be mentioned in professional reviews--is its mileage! Over 30 mpg 70+ I don't know of a viable competitor with that combination of virtues.
My initial love affair with this car has gone cold. I've had this car almost 1 year, bought it as Certified Pre Owned, and it is bordering on qualifying as a lemon. Ten trips to the dealership, mostly for brake related problems (noise, vibration, ABS/TCS lights coming on). My nearest dealership is 100+ miles away, so major inconvenience. Today, check engine light came on, a week after getting it back from the shop. Typical story. In the car's defense, a lot of the trips are due to dealership/mechanic incompetence, but isn't that part of the package? I only recommend a 9-5 if you live near a dealership and they supply loaners, and you get extended warranty.
The car has been an excellent family "sports" sedan. Dashboard layout, comfortable seats, large trunk, xenon headlights and 5-speed auto transmission w/ paddle shifters on the steering wheel are features that make this car very enjoyable. The standard Pirelli tires are not the quietest or best performing but adequate for most driving styles.
