 I read many reviews on this website, and saw where the Altima received really good ratings. I bought the basic model a few months ago. So far I can't say I'm impressed. If you need horsepower, you better keep looking. You won't find it with this car. And with the unique transmission that seems to gear down on take off, the car seems to have even less horsepower. If you need to step on the gas, get ready for a loud roar from the engine noise. It ain't pretty. Sounds like a darned airplane about to take off. I purchased the car brand new. You know the economics of buying a new car, so I'll lose my big time if I trade.
