Not impressed
 My main complaint is the engine and transmission. Reliability is good, only replacing the exhaust manifold in 85,000 miles. But the engine is extremely weak (I have SC model), and the 4 speed auto transmission shifts very rough. Engine takes 15 minutes to "warm up" before the engine and trans are even acceptable for use. The supercharged engine only performs well in dry 60-70 degree weather. I live in Michigan, and we rarely have dry 60-70 degree weather. If I ride alone and temp is optimal, the car is fun to drive, but if i carry passengers, its sluggish at best. Gas mileage is unacceptable for a V6! I rarely get over 13mpg in city driving even when i baby it! Highway mileage is no better!
