We have about 2000 miles on it thus far. Our first Buick after years of only Japanese car purchases. We haven't been disappointed. The 2008 LaCrosse's redesigned front end reduces (or even eliminates) the "grandparents' car" look with a sleeker more attractive style. The comfort and convenience package is worth the price, which adds fold-down rear seats, heated front seats, and a few other amenities. Very nice. City mileage has averaged in the high teens or 20 mpg, and highway mileage in the 28-30 mpg range. The car rides smoother and quieter than any Camry/Altima we test drove, has great acceleration, and comes with many standard features you pay more for in the Japanese cars.
Smooth and quiet ride, heated front seats, updated styling, decent gas mileage for a larger V6 car, more than adequate sound system, OnStar and XM radio.
Engine hood opening latch difficult to access and use. Very small glove box room compared to the large size of the glove box door...deceptive. Rear seat leg room is tight for tall people.
