2006 Buick Lucerne CXL V8 4dr Sedan (4.6L 8cyl 4A)
This car handles very well, doesn't get good gas mileage, but it's been reliable. But I wasted too much time in the dealership for minor but annoying fixes. Right now it's at the dealer's, again, for probably the 5th or 6th time. I had gaping wholes in the posts liner, the headliner is not trimmed at the windshield, started rattling and is ragged. I've had a rattling speaker replaced. Dashboard lights are on supposedly not because there's anything wrong with the devices they warn about, but because some absconse electrical parts are defective (unclear answers from the mechanics annoy me as well). And the latest: a bulge in the tire.
Comfortable, with all bells and whistles.
Improve interior design and fixtures attachement to the chasis. Drastically improve quality inspection.
