Just purchased gt titanium MS6 with sun roof a few days ago. Traded in the MSP. The MSP did good by me, but I got tired of the clunk issues. MSP feels light as a feather compared to the 6. Also loved the gas mileage (28-30) MPG. But, the MS6 has the power and comfort. Six speed makes this car so easy on the ears at 74 mphs. I love the ride on this car, much smoother but not too soft, since I commute 30-45 minutes each way. Wife gets to take it back to dealer for a few assessories tomorrow. Then its mines for the weekend.
