2000 Nissan Altima Sedan GXE 4dr Sedan
145K miles and still going strong
 I bought mine new and it has been amazing! Approaching 150K miles, it's just now starting to wear down (new water pump and deteriorating engine mount were a problem at 140K miles), but other than routine maintenance this car has been a gem. While under warranty I had minor problems, such as power window failing, but that's it. Spacious backseat for a compact car, lots of storage, decent sound system. Handling is sporty for a compact, as well. Interior feels more expensive than it is. Great value for the money! Gas mileage could be lots better for a small car (rarely got better than 25 mpg highway, usually 22 city). Owning this car has been a very positive experience!
