The bottom line
When you're looking at a used Altima, the story these inspections tell is one of cars that have taken hits and then been patched up, with engines that commonly leak oil, have worn mounts, and run with fuel trim issues plus active error codes. Start your check by getting under the car for oil drips and feeling the engine mounts, then hook up a scanner for those codes and give the tires a close look for wear. If you spot leaks or signs of structural work that the seller downplays, walk away or negotiate aggressively because those problems tend to pile up and turn into expensive surprises.
