I bought my Altima new and have loved it since day one! In 1999 I drove a rental on a business trip and fell in love--otherwise I never would have noticed this car. At 150,000 miles I spent some money to replace water pump and radiator, but other than that I have had almost no repair work done on this very reliable car. After 10 years, I'm still comfortable taking the car on long road trips and it looks great! The engine is great with 1 or 2 passengers, sluggish with the AC on or with a carload--what do you expect from a 2.0L engine?
I love the SE model with the spoiler! The car hugs the road and handles beautifully--I actually accelerate into curves. It looks great painted black.
Just a bit more headroom would be nice. I'm 5'10" and had to forgo the sunroof for headroom. Also a larger trunk opening would make the huge trunk much more useful.
