I have a Saturn Aura which is built off of the same platform, I have been very happy with it and have had no issues in 16k miles. I have the 4cyl, it has adequate power (similar to 4 cyl Camry/Accord/Sonata) but I really do wish I had gone for the V6. The 4 cyl is smooth and quiet though, and has a great cartridge oil filter that is simple and clean to change.
The driving experience is really positive. The ride, handling and sound insulation really do make for a comfortable and enjoyable ride. There are a lot of thoughtful features in the cabin that I really enjoy, and all of the switch gear is laid out logically, easy to operate and feel solid.
