I am the original owner of a 2004 Altima I purchased in 2003. It's a fun to drive car and has adequate head/legroom for tall drivers (as long as there is no sunroof). Acceleration and handling are very good and I generally get 23 mpg from daily driving. My biggest issues have been the following: Nissan dealerships are not good at diagnosing/fixing problems (I've used several dealerships with similar results), car won't start after you turn car on/off quickly in cold weather (This is a known "cold start" issue that, based on my experience, Nissan generally does not acknowledge/fix), parts can be expensive. While I enjoy driving the car, my experiences with Nissan are often disappointing.
