i just love this car.i bought in 2008 it has 25,000 miles on it.now it has 125,000 and it still drive the same.just change air filter that was it.

Stock ride is a little "floaty" (for those who prefer a more performance oriented ride), and the car is a little under powered, as compared to 2010 V6's or turbo 6's.. but still a great car with a CLASSIC look!
I purchased this car for my wife in October 2006. She loves the car - I enjoy driving it too when I'm allowed to do so. My only complaint is the high cost of maintaining it. The cost may be a function of the high dealer cost here in Charlotte - I'm reluctant to take it to an independent - but perhaps I should change my reluctancy. I've been informed that I should change the spark plugs ever...
