 When we purchased my Altima, it was a cheap 3500. Except, it wasn't. My parents ended up dishing out another 1k to fix some of the issues it had in the first week.  The O2 sensors had to be replaced, it burned oil, there was a coolant leak and blockage. The heat also didn't work properly as you had to drive 40mph for it to kick in. Plus some other issues such as misfiring and me being stranded on a busy backroad. The mpg also went down when we tried to slow the burning with stop smoke. All of this and more happened before I sold it for a measly 1k, which is more than I thought we would receive. Granted, my parents never told me or they didn't know that this particular vehicle had been in two accidents and had flood damage. Of course, the other '05 Altima they got for my sister also burns oil and other issues have come up in the period she has had it. I wouldn't recommend buying a Nissan.
