I'd also like to nominate another household sedan we've had.
We had a 2004 in charcoal gray that was almost complete rubbish. It might have been a decent car if we had the LS package and not just the base model.
Here are its list of faults:
The interior design was sterile and uninspiring and had next to nothing in terms of fit and finish. Since we also had a bench seat in front, that means we also had the column shifter, and I can remember thinking that the interior wouldn't look out of place in a truck. The plood was nasty as well. The backseat was about as comfortable as a park bench made out of cinderblocks and the front seats were just as bad.
Yes, I know we picked up the base model Impala, but this car was brand new for the 2004 model year. So was I asking too much when I realized the car should have more standard features, like say ... a CD player, for one? Yes, this car did in fact have a cassette deck and, yes, it came from the factory that way. I was also expecting a tachometer, but instead the only instrumentation was a temperature gauge, speedo, and fuel gauge. By the way, before the car was traded in for the G6 I mentioned earlier, the speedometer never worked correctly.
The transmission had started to slip at 40,000 miles. Quite badly, too.
Those gawd-awful plastic wheel covers. I think wheel covers made out of actual recycled $h! and used tampons would have been better. These had started to fade to yellow at 34,000 miles or so.
I will give the Impala this: it did handle pretty great.
