Your gut impression is important. The 2010 is better than 2009, but it sure isn't great. If you had doubts you made the right decision - there are lots of fine riding cars out there you can find without odd suspensions. They may not be as nice a package, but...
UPDATE: THIRD DRIVE. Taking some good advice from the forum members I decided to take a different V8 with Tech on some city streets as well as the highway. My total test run took approximately 40 minutes. This time I checked all the tires and made sure they were all 33 lbs cold. They started at 36 cold before adjustments. This car just came in without carpets installed etc. I didn't notice any steering issues at all this time. The steering on the V8 is extremely tight. The V8 is exceptionally smooth and powerful with nice shifts from the transmission. Now for the part I am concerned about. After driving through many uneven and irregular road services, looking for speed bumps, and highway driving as well, I can only describe the ride as jittery or a car on caffeine. It reacted to almost every irregularity with direct transference to the driver's seat. Even the salesman had to admit he felt it, but of course stated this is a sport ride and is supposed to be firm. The jury is out for me. I know I can get this car at a GREAT price, but I'm not sure that after drving for lenghly periods of time, I will be happy. I love every aspect of this car except the ride. It would be great if they let me take the car overnight, but I know that won't be happening.
