I purchased this car to replace my 2004 Toyota Prius. Now granted I gave up a few things, like space in the back (40 cubic feet in the Prius versus 10 in the Altima)and about 16 MPG on average (50 MPG with the Prius versus 34 in the Altima), but I gained a much more agile and quicker car, not to mention some added luxury. I purchased the 2010 Nissan Altima Hybrid fully loaded and for 30k, you'd be hard pressed to find a better deal elsewhere. The automotive press says that the car is noisy, but no more so than any other hybrid, though the regen brakes do make some noise more than the Prius does.
The backup camera and the DVD player in the car! Not to mention how stylish the car is compared to the Prius. It saves money, but it has just enough of an edge to pronounce that it's a Nissan! How cool is that!
Fog Lights...they aren't available on the hybrid and HID headlights instead of halogen, but other than that...nothing!
