If a 93.5 P10 has a sunroof, it came with a factory alarm system and remote. (I was amazed the seller of my P10 still had the factory remote with trunk opening button, Vadim)
All 93.5 P10s came standard with air bags.
93.5 is last year of OBD I in the P10 chassis.
A 99 trans is just as weak as the rest, AND the 93.5-96 P10s do have SLIGHTLY better gearing than previous versions. (Getting picky now, just helping Vadim prove all points)
