Well...

The 92 has a slightly beefier B230F engine. It also has ABS brakes, driver's airbag, SRS-linked seatbelts, side impact protection system, upgraded headrests, locking differential.

The trans (non-turbo) is an AW70L with lockup torque converter for slightly better efficiency.

The A/C controls are a little bit more user friendly, save for the "A/C Off" button.

The 92 has a Rex/Regina fuel injection system on the non turbo models. This system is, I would say, "as reliable" as the Bosch system, but in different ways. There is no airflow meter (less expensive) but there is a MAP sensor. (Still less expensive). The ignition coil is more expensive and more failure prone than the Bosch system coils. There is a single in-tank pump on Regina-equipped models. That is good--only one pump. It is also bad--one, more expensive pump.

Mostly the Regina components ar ea little more pricey, but not tremendously so. The Regina system is virtually unavoidable in 90-93 naturally-aspirated models, exept for 50-state models.

The 92 was certainly the most feature-rich of the 700 line. IT carried on into the 900 series line, which eventually added dual airbags (but not a whole lot else on 940 wagons).

The earlier 700 series cars were excellent as well, but the later ones were better equipped overall.
