Well on your S13 models (89-94), you have 2 "major" options. 89 and 90 models have a single overhead cam, and a "pignose" front bumper. 91-94 (94 only coming in convertible) models have dual overhead cam, and a "shark-nose" front bumper. Both engines are pretty darn good, with the DOHC having slightly more aftermarket support.
240s (like most Nissans of the time and earlier) suffer from rust. Check the rocker panels and the strut towers. Also, if you are looking at an S13 hatchback, and it has a factory spoiler on it, you can pretty much bank on there being rust under that bad boy.
Other than that, some S13s suffer from some wiring harness issues (engine room harness maybe, causing erratic idle/timing, speed sensor harness issues causing no speedometer function, etc). S13s generally have crappy seats. S14 (95-98) seats bolt right in.
The engines, transmissions, and rear differentials are pretty bullet proof, although they can suffer from the general oil leaks, etc.
