Have driven Cadillacs for over 27 yrs, my last being a 2001 DHS. First Buick ever. My Buick Super is giving me excellent performance. No wind noise. Fuel economy is what is to be expected with a 292 HP Northstar engine, (20mpg city driving) and absolutely fun to drive. A great many options comes with this vehicle. I've also saved several thousand by buying the Buick over the Cadillac with just about all the same options. Completely satisified
Side blind zone alert and lane departure warning is a great added feature. Great radio sounds from the 9 speakers. Many other options are now standard equipment.
Drivers arm rest should be longer with more room to place articles inside. Make the front drivers and passenger seats 60/40 with slightly more comfort.
