2007 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)
Many features are very difficult to master. Even the seat controls are difficult to master. The width of the driver's floorboard is not wide enough for comfort and seem to crunch large feet. I do like many of the features such as backup warnings and overall appearance. If I had the purchase to do over I would select a different vehicle.
OnStar and navigation system even though the navigation system is difficult to master. Memory seat is a great feature if I can master its use.
