Stop with the Toyota crap. I don't care to hear it. I owned a Rav 4 before I owned the Durango listed, and it was no better in reliability. I lost a timing chain at 52,000 miles in it, and always had a problem with the gauge cluster.
I bought the Impala because I wanted it.
I had a 2003 Durango review on here with close to 300000 miles; a fleet maintained company car.
The engine used 1 quart of oil every 5000 miles when it was changed. And that was often. Same engine, and had 1 trans replaced.
I know a guy with a 98 Corvette with 189000 miles on it with only routine maintenance; fluids, tires, serpentine belt and idler arms. The LS engines are available in other GM models as well.
How about the new Cadillac with the 6 speed manual for 60k. Great car for the money, with incredible hp and performance.
I also like the Impala SS.
What exact year and model do you own? You neglected to mention that in your broad based sweep of a brush.
Yeah, HA HA HA, the Government STILL owns 26.5% of GM. But the government NEVER creates negative propaganda about those they oppose, now do they? HA!
So you are the original poster... the one with the lousy running brand new Chevy, and you don't want to hear about Toyota's anymore? Are you having seller's remorse? I'm sorry you had bad luck with your Toyota. Seems you just have bad luck period with cars though, doesn't it?
Maybe you should try Honda next?
17:15 sure likes to be amused. I buy on quality, features, styling and benefits, not percentages. Do you test drive vehicles and buy, or do you discuss percentages of corporations?
What's it to you if the guy likes his Impala? Ever hear of the millions of new cars that Toyota had to recall because they don't know how to design an accelerator???
Drive your boring Japanese "me too mobiles" and leave decent Americans alone who are still proud to drive a domestic car.
And please don't bother writing on here how your Camry was built here in the US. I have heard it all a hundred times before, and could care less.
I drive a '99 Tercel during the winter months. Boring but reliable. The old power-train quality is probably superior to their new stuff...
So many variables, who knows what they sell us at the pumps. Go with the highest octane available, and hope that's what they are selling you. If it is, you will pay more, but get better mileage and performance all around. Then take that car out and punish it, by putting your foot to the floor for a good run down the freeway for about 5 miles, and watch the black smoke you leave behind when your foot is pinned to the floor. CLEAN IT OUT MAN...
I am the original writer of this review.
After fighting with the dealership multiple times with the same issue, as well as having issues with the transmission and getting a "engine power reduced, service stabilitrak" code twice, the car was traded in 2 weeks ago on a brand new 2013 Honda Civic.
It's a shame that the Impala only had 43,000 miles on it when traded in, and it was completely ridden with issues before trading it in. I've had multiple domestic and Japanese (all Hondas) vehicles over the years, but when I weighed out the reliability, the Hondas I had were far more reliable (and had very few issues in the first place), so I am sticking with Honda for good.
I know I should be supporting an American automaker, but when I've had nothing but issues with them, I cannot do that. Especially when I need a car to rely on to get myself to work on a daily basis, which won't break down and leave me stranded 3 times like the Impala did.

One more quick comment.
I did do what the March 2012 comment suggested and ran the higher octane gas. Punching it out on the open road made it shudder a bit the first couple times, but it did blow out a lot of black (and some white) smoke like he predicted. The shuddering started to go away a bit as the engine got cleaned out. It didn't help the original problem, but it did seem to help clean things out.
Hope that helps.
