2001 Nissan Sentra Sedan SE 4dr Sedan (2.0L 4cyl 5M)
Not reliable
 I got this car used, in mid 2015 (so nearly 15 years old) but with less than 120,000 miles on it. I liked this car, for the most part. It's loud (and not because of a large engine) and it's no luxury vehicle, but it is fine. However, there are small things: the stereo is not very good (especially if you have to turn it up for reasons I will get in to), the arm rest compartment broke, parts of the interior rattle and vibrate at highway speed, the headlights are not great, and the tires wore out relatively quickly.  Now on to the big things, the A/C went out and it was a multi-thousand dollar job (apparently the labor is complicated because of how the car is built), I did not get this fixed. As a result, I was driving with the windows down all summer, even on the highway, so if I wanted to listen to music I had to turn the stereo up high, and noticed diminished sound quality. The driver's window control does not always work. The sun roof broke, also a multi-thousand dollar job I did not bother with. Just recently, the ECM broke (so I couldn't even start the car), the neutral switch also broke, and my car is still currently in the shop because it is now idling too high, and the mechanics cannot figure out why. I also had to fix brakes, and brake calipers, suspension replacements, and a few other things. Having had this car for about 12 months, it's been in the shop for nearly 10% of that, and has cost me a lot in repairs. I would not expect to have these problems until the 200k mark at least.
